SUMMARY:Photonics Initiative Spring 2024 Seminar Series: Prof. Zhi Ning Chen
DESCRIPTION:Zhi Ning Chen\nNational University of Singapore \nDate:\nFriday\, June 14\, 2024 \nTime:\n10:30am – 11:30am \nLocation:\n5th Fl. Data Viz Room \n\n\nPrior-knowledge Guided Machine-learning Enabled Metalens Antenna Design\nAbstract –  The design of antennas aims to meet the specific requirements of a system. This design relies on materials\, fabrication processes\, and design methodologies. Besides natural materials\, we have introduced metamaterials—artificially engineered structures that exhibit unique electromagnetic properties not found in nature—to expand the boundaries of antenna design. Furthermore\, we have explored new design methodologies to extend these boundaries. \nTraditionally\, antenna design begins with basic designs\, which are then modified or optimized to meet the specifications. However\, this approach has limitations in achieving optimal performance due to constrained degrees of freedom (DoF). These limitations arise from physical constraints such as volume restrictions and feeding structures\, as well as restricted design space regarding the selection of viable structures or parameters in the design process. Therefore\, deep learning algorithms are being utilized to significantly increase the degrees of freedom (DoF) in antenna design. This will expand the antenna design space and hold promise for enhancing antenna performance. \nThis talk will focus on outlining innovative approaches to antenna design. Specifically\, it will explore the prior-knowledge-guided deep learning-enabled synthesis method and demonstrate its utility in enhancing the performance of metacells and metalens antennas. \nBio – Professor Zhi Ning Chen got his two PhD degrees in China in 1993 and in Japan in 2003\, respectively. Currently\, Dr Chen is working as a Provost Chair Professor of Department of Electrical and Computer Engineering\, National University of Singapore. He is serving as Director of Advanced Research and Technology Innovation Center (ARTIC) of College of Design and Engineering\, National University of Singapore. He elevated Fellow of the Academy of Engineering\, Singapore in 2019\, Fellow of the Institute of Electrical and Electronic Engineers (Fellow of IEEE) in 2007\, Fellow and Vice President of Asia and Pacific Artificial Intelligence Association in 2021\, and Fellow of Chinese Institute of Communications 2023. He is the recipient of IEEE AP-S John Kraus Antenna Award (2021). He has published 710 papers\, 7 books\, and 34 patents. He has been the founding general chairs of IEEE International Workshop of Antenna Technology (iWAT in 2005)\, IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP in 2012)\, Marina-Forum (Mar-For in 2021) and two important technical conferences. \nThis is an in-person seminar.

SUMMARY:Guest Speaker: Dr. King Hang Aaron Lau\, PhD
DESCRIPTION:Peptoid Self-Assembly: from Minimal Peptoids to Cell Membrane Interactions\n  \nKing Hang Aaron Lau\, PhD\nAssociate Professor (Senior Lecturer) in Materials and Bionanotechnology\nDepartment of Pure and Applied Chemistry\, University of Strathclyde\, Glasgow\, UK \n  \nAbstract- N-substituted glycine “peptoids” are close structural isomers of peptides and can be synthesized with both natural and non-natural sidechains. Their self-assembly is of great interest not only because they represent a “control set” to probe the fundamental requirements of peptide assembly but also because\, firstly\, they expand the range of assembled structures possible\, and secondly\, they can exhibit simplified sequence design rules due to the elimination of intra-backbone hydrogen bonding. This presentation will introduce our work in recent years to investigate the behavior and biofunctionality of peptoid assemblies based on a range of sequence lengths and chain-end modifications. In terms of “minimal” peptoids\, we recently discovered that certain single C-amidated monomers may form novel 2D crystalline layers at the water-air or water-oil interface that we term interfacial crystals. We were also the first to report the ability of water-soluble peptoid trimers to assemble into pH stable\, sequence-dependent morphologies\, including uniform nanofibers. The unique π-interactions originally observed in fluorescence spectroscopy are now supported by atomistic computation studies. For longer sequences\, by introducing a backbone bending linker in lipo-peptoid amphiphiles and by balancing the peptoid and hydrophobic tail lengths\, we have been able to modify the cytotoxicity of antibacterial sequences. Finally\, with free-floating peptoid nanosheets assembled from long amphiphilic alternating sequences\, we recently are also observing the potential to direct stem cell osteogenesis based simply on physical contact interactions. Based on these synthetic peptoid assemblies\, we hope to demonstrate the expanded possibilities in bioinspired materials enabled by non-canonical sequence-specific polymers and considerations of biophysical effects more generally. \n  \nBIO– Aaron is associate professor in materials chemistry at the University of Strathclyde. He obtained his ScB and ScM at Brown\, PhD at the Max Planck Institute for Polymer Research\, and postdoctoral training at Northwestern. He then started his lab at Strathclyde as a founding member of its Bionanotechnology initiative. Aaron’s experimental research seek to deepen our biophysical chemistry understanding of macromolecules at surfaces and interfaces\, including self-assembly and membrane interactions. This fundamental knowledge is applied to the development of novel bio-\, nano-\, and sustainable bioinspired materials. The main molecular platforms are “peptoids”\, a highly convenient and designable peptide-mimetic synthetic platform\, and tannic acid\, a versatile and multifunctional molecular “integrator”. Current projects include peptoid self-assembly\, antimicrobial peptoids\, acoustically functional structures\, and polyphenol water remediation sorbents. \n

SUMMARY:Guest Speaker: Dr. Ayala Lampel\, PhD
DESCRIPTION:Charge-Mediated Interactions Affect Enzymatic Reactions in Peptide Condensates\nAyala Lampel\, PhD\nShmunis School of Biomedicine and Cancer Research\, George S. Wise Faculty of Life Sciences\, Tel Aviv University\, Tel Aviv\, Israel. Center for Nanoscience and Nanotechnology Tel Aviv University\, Tel Aviv\, 69978\, Israel Sagol Center for Regenerative Biotechnology Tel Aviv University\, Tel Aviv\, 69978\, Israel Center for the Physics and Chemistry of Living Systems Tel Aviv University\, Tel Aviv\, 69978\, Israel \nAbstract- Biomolecular condensates\, formed through liquid-liquid phase separation (LLPS)\, act as enzymatic reaction centers in cells by increasing the local concentrations of enzymes and substrates\, thus facilitating reaction kinetics and regulatory mechanisms. Inspired by these natural systems\, synthetic condensates are increasingly being developed for diverse applications\, including payload delivery\, sensing\, and as microreactors where enzymatic reaction kinetics can be modulated by factors such as pH\, viscosity\, and enzyme-substrate co-localization. We investigated how the physicochemical properties of enzymes and substrates influence condensate formation and their function as microreactors. For this\, we employed a minimalistic complex coacervation system of oppositely charged LLPS-promoting peptides\, and focused on two simple enzymatic model systems\, cellulase and alkaline phosphatase\, which differ in molecular weight and isoelectric point. Our findings demonstrate how electrostatic forces within condensates influence their role as microreactors. Specifically\, the ability of condensates to encapsulate or exclude phosphatase\, cellulase\, and their substrates—which is pivotal for the regulation of reaction kinetics—is determined by enzyme surface charge\, substrate charge\, and condensate charge stoichiometry. These results highlight the potential of utilizing electrostatic forces within condensates to modulate enzymatic reactions\, providing critical insights for the development of synthetic condensates as microreactors in biotechnology and materials science. \nBIO– Ayala Lampel is an assistant professor (senior lecturer) at Tel Aviv University.

SUMMARY:Photonics Initiative Seminar: Michael Scalora
DESCRIPTION:Light-Matter Interactions at the Nanoscale: Harmonic Generation from Metal/Vacuum Interfaces and Novel Aspects of Radiation Reaction \nAbstract – In noble metals a patina of free electrons extends out into free space and vanishes within a fraction of an atomic diameter. We discuss the possibility and consequences of the existence of such a free electron layer\, acting as an epsilon-near-zero medium. Just as classical macroscopic electrodynamics cannot discern either individual atoms or field fluctuations between atoms\, it is similarly unable of discriminating the rapid decay of the free electron spill-out density within a distance that is less than an atomic diameter. The best one can do is treat the boundary as a layer of free charge density having thickness equal to a single spatial discretization step of unknown average density\, equivalent to a delta-function. Under these conditions we predict that if this boundary layer exists it will display enhanced pump absorption and decreased nonlinear thresholds. Finally\, we will discuss a new formulation of radiation reaction that supplants the Abraham-Lorenz classical theory and applies to non-relativistic electrons of finite size. The introduction of an explicit reaction force in the Newtonian equation of motion leads to a new hydrodynamic equation that offers novel insight on the influence of damping in generic plasmas\, metal-based and dielectric nanostructures. \nBio – Michael Scalora received a B.S. degree in physics from Montclair State College\, Montclair\, NJ\, and M.S. and Ph.D. degrees from Rensselaer Polytechnic Institute\, Troy\, NY.

SUMMARY:Photonics Initiative Seminar: Guancong Ma
DESCRIPTION:Non-Abelian Braiding with Sound and Light\nAbstract – Many physics laws and mathematical rules are insensitive to order. For example\, the addition of numbers disregards the sequence order\, e.g.\, 1+2+3=3+1+2. However\, such a commutative property does not always hold. When the outcomes of a set of operations depend on the execution order\, they can become “non-Abelian.” In the 20th century\, non-Abelian mathematical frameworks have played profound roles in formulating many fundamental laws of modern physics. Famous examples include the classification of hadrons and the unification of electro-weak interactions. Classical physics\, such as mechanics\, electromagnetism\, and optics\, were well established before non-Abelian theories came into play. However\, this does not mean non-Abelian effects are absent in the classical world. One prominent example is a Rubik’s Cube—the moves made on the cube do not always commute: two sequential moves done in different orders do not necessarily get the color palettes to the same layout. We then ask: how and when non-Abelian phenomena arise in classical waves? Delving into this question\, our recent works leverage Berry-phase matrices\, which capture the adiabatic evolution of multiple states\, to realize non-Abelian braiding in acoustics [1] and photonics [2]. Here\, the braiding operations are implemented using coupled waveguide arrays\, which are adiabatically modulated along the guiding direction to enforce a multi-state Berry-phase matrix that swaps the modal dwell sites. The evolution of the guiding modes maps to the generators of braid groups. The non-Abelian characteristics are revealed by switching the order of two distinct braiding operations involving at least three modes. Our results offer new perspectives in exploring novel wave-controlling schemes for future technological applications [3]. \n[1] Z.-G. Chen\, R.-Y. Zhang\, C. T. Chan\, and G.

SUMMARY:Photonics Initiative Seminar: Jonathan Pelliciari
DESCRIPTION:Co-sponsored with CCNY. \nUsing Resonant Inelastic X-Ray Scattering to study quantum materials \nAbstract – Modern light sources like the NSLS-II at Brookhaven National Lab deliver bright tunable photons in a wide range of energies from the THz regime up to 100 keV. This allowed the development of scattering techniques relying on the use of atomic resonances enabling the access to the electronic degrees of freedom in materials. Resonant Inelastic X-Ray Scattering (RIXS) is one of these techniques and thanks to the massive development in instrumentation and theory is playing a significant role in the study of quantum materials with contributions in multiple fields such as superconductivity\, quantum magnetism\, 2D materials\, and lately single photon emission. The sensitivity of RIXS to bosonic excitations of different nature (spin\, orbital\, lattice\, and charge) can provide microscopic information on materials as a function of energy and momentum. In my seminar I will start by introducing RIXS its capabilities and limitations\, followed by a description of the experimental components needed to perform high-resolution RIXS and the solution that we developed at BNL. I will then move forward by highlighting three scientific cases in different fields. The first will involve our investigations on superconducting infinite layer nickelates where we studied the evolution of the spin dynamics across the superconducting dome akin to past studies on the cuprates. The second case regards the study of quantum emitters in hBN where in collaboration with CUNY we could unveil vibronic states and connect them to the signals detected in photoluminescence possibly identifying N2 molecular vibrations as the key for the emergence of quantum emission. Finally\, I will conclude by highlighting one of our studies on excitons in 2D van der Waals magnets where we could detect their nature\, evolution as a function of charge transfer energy (and hybridization)\, and their dispersion in momentum space. \n[1] Ament et al.\, Rev.

X 14\, 031007 \nBio – Jonathan (Johnny) Pelliciari is an Associate Scientist at NSLS-II where he uses advanced scattering techniques (including Resonant Elastic and Inelastic X-Ray Scattering RIXS) to investigate the electronic properties of quantum materials. He got a Bachelor and Master degree in Chemistry at the University of Modena and Reggio Emilia (Italy) and a PhD in Experimental Condensed Matter Physics at the Paul Scherrer Institute and University of Fribourg/Freiburg (Switzerland). His research involves the study of electronic orders such charge and spin density waves and the elementary (spin\, charge\, orbital\, and lattice) excitations in superconductors\, low dimensional systems\, and materials displaying metal-to-insulator transitions. Overall\, his research interests span different physical phenomena such as ultrafast phenomena\, unconventional charge density waves\, spin excitations\, superconductivity\, 2D van der Waals systems\, spin liquids\, and quantum emitters. He developed a laser-RIXS setup commissioned at the SIX beamline to study quantum materials and their ultrafast transitions. \nHe has several active collaborations with external universities and research institutes (CUNY\, Stanford\, MIT\, Yale\, Harvard\, University of Zagreb\, and PSI) on different projects.

SUMMARY:Guest Speaker: Job Boekhoven\, PhD
DESCRIPTION:Regulating molecular assembly with chemical fuels—Spinning ribbons\, dissipative structures\, and an approach towards synthetic life \nJob Boekhoven\, PhD\nDepartment of Bioscience\, Technical University of Munich \nAbstract-Molecular self-assembly is the process in which molecules combine into superstructures held together through non-covalent interactions. Over the last decades\, supramolecular chemists have perfected this art\, and we can now create Gigadalton structures in which each atom is placed with angstrom precision. More importantly\, the unique properties of the emerging assemblies have found their way into everyday life\, like\, for example\, the liquid crystals in our displays. Nevertheless\, biology entirely overshadows us regarding assembly with molecular building blocks. Indeed\, the biological cell has the same molecular toolbox for creating structures; it also uses non-covalent interactions to hold molecules together. Biology uses another trick. Biological structures are governed not only by non-covalent interactions but also by reactions forming covalent ones. Arguably\, molecular self-assembly offers the structures; chemical reactions govern the dynamics and functions of these structures. Biological structures are sustained and regulated in the non-equilibrium regime through chemical reaction cycles that convert energy. The implications\, rules\, and mechanisms there are poorly understood. \nIn this lecture\, I will discuss my team’s effort to elucidate the rules of non-equilibrium self-assembly regulated by chemical reaction cycles. Next\, I will describe a simple yet versatile chemical reaction cycle that can be coupled to self-assembly to create chemically fueled assemblies. Finally\, I will highlight three recent examples of chemically fueled\, non-equilibrium assemblies with vastly different properties than their in-equilibrium counterparts—ribbons that spin spontaneously as they consume fuel and dissipative droplets that periodically form and dissolve when fueled continuously. I will close the lecture with our vision towards synthetic life. \nBio-Job Boekhoven is an Associate Professor at the Bioscience Department of the Technical University of Munich in Germany. He received his PhD in Chemistry under Prof. Jan van Esch and Prof. Rienk Eelkema from the TU Delft in 2012. After a postdoc at Northwestern University (2010-2013)\, he started his independent group in 2016 at the Institute for Advanced Study at the Technical University of Munich as a Rudolf Mössbauer Professor. His honors include an ERC Starting grant (2016) and an ERC Consolidator grant (2024). He has received the VCI – Dozentenpreis and is a Max Planck Fellow in the school Matter to Life. \nJob Boekhoven is developing tools to regulate the self-assembly of molecules the way biology does. He is best known for his work on chemically fueled reaction cycles that control the ability of molecules to assemble or phase separate. The resulting materials show exciting new properties\, such as their intrinsic ability to self-heal or their controllable lifetime. Moreover\, the chemically fueled assemblies manifest features we usually associate with living cells\, like the ability to emerge\, decay\, or even self-divide.

SUMMARY:Photonics Initiative Seminar: Yakir Hadad
DESCRIPTION:Exact formulation of the mutual particle-cavity dynamics and its use for the study of loss threshold phenomenon under magnetization\nAbstract – Light-matter interaction plays a pivotal role in pushing forward nanotechnology. A particularly important setup involves a resonating particle\, say an emitting molecule or a macroscopic quasi-statically resonating plasmonic or ferromagnetic sphere\, that is located inside a cavity. \nIn this work\, we provide an analytic formulation for the exact calculation of the mutual dynamics between a resonant particle and a rectangular cavity in which it is located. The particle is assumed to be small on the wavelength\, and thus\, its excitation is dominated by a dipolar response that can be described using the discrete dipole approximation and polarizability theory.  The dipolar response depends on the particle’s polarizability function which encapsulates the particle’s materials and geometry\, and on the local field acting on the particle. In principle\, the latter is nothing more than the backscattering of the particle field by the cavity walls.  However\, its derivation may be challenging since it involves a three-dimensional singularity subtraction of the Green’s function in the cavity and the Green’s function in the free space that are differently represented. In this work\, we discuss the use of a recursive ladder-type process involving alternative Green’s function representations to calculate the local field in a computationally efficient and numerically stable manner. Using this approach\, we solve exactly several strongly coupled particle-cavity systems and calculate the collective resonance frequencies of the system. \nAs a particularly interesting example\, we focus on the case when the plasmonic particle is subject to a static magnetic field\,  . In this case\, its gyrotropic response gives rise to non-reciprocal dynamics of the ambient surroundings.  This dynamics depends on the particle’s excitation\, which in turn depends on the gyrotropic material damping rate  . Thus\, intuitively speaking\, the heavier the gyrotropic material loss is\, the weaker the non-reciprocal response will be. This is indeed the case when the particle is located in free space. However\, when the gyrotropic particle is placed inside a cavity\, we show that the non-reciprocity measure is robust against material loss up to a specific loss threshold\,  that depends on the magnetic biasing . \nBio – Dr. Yakir Hadad received the B.Sc. and M.Sc. degrees (summa cum laude) in electrical and computer engineering from the Ben Gurion University of the Negev\, Be’er Sheva\, Israel\, in 2006 and 2008\, respectively\, and the Ph.D. degree in physical electronics from Tel Aviv University\, Tel Aviv\, Israel\, in 2014.\,From 2015 to 2017\, he was a Post-Doctoral Fellow with the Department of Electrical and Computer Engineering\, The University of Texas at Austin\, Austin\, TX\, USA.

SUMMARY:Guest Speaker: Tanja Weil\, PhD
DESCRIPTION:Synthesis of Interactive Peptide Nanostructures in Living Systems \nTanja Weil\, PhD \nMax Planck Institute for Polymer Research\, Germany \nAbstract- We explore controlled chemical reactions in complex living systems to generate drug molecules\, synthesize peptide nanofibers\, or build new cellular compartments. The introduction of bioresponsive groups enables us to control peptide self-assembly inside the living cell. These groups react in a controlled fashion with cellular stimuli\, including pH\, reactive oxygen species\, glutathione\, and light. The synthetic intracellular peptide nanostructures can interfere with cell respiration\, metabolism\, they can induce controlled cell death\, or activate T-cells. Additionally\, peptide nanostructures can be integrated into the extracellular matrix\, where they facilitate virus binding and enhance the uptake of viral vectors. To optimize the amphiphilic peptide sequences of self-assembling peptides with regard to their multiscale structure formation and bioactivity\, we employ data mining and machine learning tools. \n \nFigure 1. Bioresponsive caged peptide monomers enter living cells and undergo chemical transformations initiated by cellular stimuli and form supramolecular peptide nanofibers that can affect cellular processes. \n\nChagri\, S.; Ng\, D.

SUMMARY:Thesis Defense: Shixiong Yin
DESCRIPTION:Enhanced Light-Matter Interactions in Complex Photonic Systems \nMentor: Andrea Alù \nAbstract  \nInteractions between light and matter are fundamental to breakthroughs in lasers\, sensing\, imaging\, spectroscopy\, energy harvesting\, and quantum information processing. As a result\, significant recent efforts have been geared towards enhancing and controlling light-matter interactions to advance these applications and technologies. Complex engineered photonic systems\, often involving nanoscale designs of photonic components\, have provided fertile grounds to manipulate light unprecedentedly\, achieving extreme control over interactions among photons and between light and matter. In this dissertation\, we exploit four types of complexity to enhance light-matter and light-light interactions in various photonic platforms. \nFirst\, we start by tailoring the spatial complexity in photonic designs\, which can stimulate unusual light interactions with plasmonic materials. In a one-dimensional metamaterial\, i.e.\, an artificially engineered periodic structure\, we show that perturbing the discrete translational symmetry can induce a topological knot in reciprocal space. It enables strong nonlocal coupling between a dark mode and a brighter surface mode\, which offers new opportunities for efficient sensing and Raman scattering. \nIntroducing complexity in the material constituents together with deliberate spatial designs\, we further explore how nonlinearities in metamaterials unleash novel forms of controlling light emission\, leveraging strongly enhanced interactions with light. Besides\, blending different types of materials can also push the limits of complex photonic designs. We design an ultrasmall nanocavity hybridizing two distinct materials — a high-index dielectric encapsulated by the low-loss metal\, demonstrating record-high Purcell enhancement. The proposed hybridized nanocavity is expected to enhance quantum emission and strong coupling substantially. \nAs another degree of freedom\, complexity can be introduced in the temporal dimension. Time variations in material properties provide a new knob for complex photonic designs. Among them\, time-interfaces\, realized by switching the properties of the entire medium in time\, introduce striking complexity in wave dynamics. In a transmission-line metamaterial\, we have observed time reflections at a photonic time interface and associated broadband and ultrafast frequency translation for the first time. Combining multiple time interfaces in the same platform\, we realize a passive photonic time crystal\, which holds the prospect of extreme interaction with light with zero energy cost\, inaccessible in either time-invariant or conventional time-varying systems. \nFinally\, we harness the complexity in the frequency domain. Complex spectral responses and modal patterns can arise in wave-chaotic systems. In this context\, we realize coherent control over photon-photon interactions in a chaotic photonic microcavity involving over a thousand optical modes. Efficient control of its radiation is further demonstrated via reflectionless scattering modes\, paving the way for efficient energy harvesting\, routing\, and conversion. \nZoom Meeting ID: 722 951 7086 Passcode: 2024 \nMembers of the doctoral faculty are invited to attend.

SUMMARY:Thesis Defense: Seungri (Victor) Kim
DESCRIPTION:The Effects of Nanoconfined Liquid Properties on the Water-Responsive Behavior of Bacterial Cell Walls\n  \nAbstract: Water-responsive (WR) materials have the ability to mechanically swell and shrink in response to changes in relative humidity (RH). These WR materials are used by many biological systems to perform essential tasks; for example\, pinecones use WR materials to release their seeds in dry environments\, and wheat awns open and close to propel seeds into the soil\, driven by daily RH changes. The WR actuation of some biomaterials is extremely powerful\, for example Bacillus subtilis cell walls display record-high actuation energy and power densities of 72 MJ m-3 and 9.1 MW m-3\, surpassing those of all existing muscles and actuator materials. They hold great potential to be used as high-performance actuators for various applications\, including energy harvesting\, robotics\, and morphing structures. However\, the fundamental mechanisms of WR actuation are still poorly understood. Despite the unclear WR mechanism\, recent studies have provided compelling evidence of the critical role that the properties of nanoconfined water play in these observed high-power WR actuation\, and thus\, adjusting the properties of nanoconfined water should substantially affect WR behavior and performance. \nThis thesis investigates the role of nanoconfined liquids in the WR actuation of bacterial cell walls\, focusing on how modifying their behavior can improve WR performance. In this research\, cell walls of E. coli\, S. aureus\, S. cerevisiae and B. subtilis were extracted and used to investigate the properties of their nanoconfined water. Based on these findings\, we further explored the effects of kosmotropic and chaotropic solutes\, known to stabilize or disrupt hydrogen bonding networks\, on the WR performance of B. subtilis cell walls. We discovered that cell walls treated with low-concentration kosmotropic solutes exhibited a significant increase in WR actuation energy density\, reaching 103.3 MJ m-3. However\, higher concentrations of kosmotropic or chaotropic solutes led to decreased WR performance. Our observations suggest the presence of an optimal range for kosmotropic and chaotropic treatments to enhance WR energy density. These findings could be explained by the impact of the solutes on hydration forces and intermolecular interactions\, which affect the ultimate WR pressure. This\, in turn\, provides a pathway towards achieving superior WR actuation performance and advancing the development of high-work-density actuator materials for diverse industrial applications. \n  \nPlease use the Zoom meeting link below if you cannot attend in person. \nMeeting ID: https://ccny.zoom.us/j/8366033109?pwd=WTZZVzRNZllQUWhsc2RnRHdiN1hWUT09 \nLink to Announcement \n

SUMMARY:Photonics Initiative Seminar: Bing Cheng
DESCRIPTION:Terahertz probes of quantum matter: from pairing symmetry to high harmonics\nQuantum materials often harbor emergent orders and phases that reveal themselves at low-energy scales\, around 1 to 10 meV. To investigate these collective behaviors\, we turn to the terahertz energy regime—a crucial window for probing and controlling quantum phenomena. In this talk\, I will present our latest breakthroughs in unraveling the superconducting gap structure of the newly discovered unconventional nickelate superconductors— a topic that has sparked intense debate and remains unresolved. Using both linear and nonlinear terahertz spectroscopy\, we uncovered multiple evidence to demonstrate a cuprate-like d-wave gap structure in nickelate superconductors\, providing key insights to steer future research in this field. Expanding beyond understanding\, I will broaden the discussion to the manipulation of quantum materials through light. I will show how we harness intense terahertz pulses to drive the electronic structure of a Dirac semimetal\, leading to the observation of record-breaking terahertz high harmonics. Our findings position topological materials as promising platforms for delving into high harmonic generation and strong-field physics. \nBrief Bio: Bing Cheng earned his Ph.D. in Johns Hopkins University in Sep 2019. Then he moved to Stanford\, and Ames National Lab\, working as a postdoc researcher. At present\, He is working as a research fellow in Prof. Mengkun Liu’s group at Stony Brook University. His research mainly focuses on discovering and understanding exotic quantum phases of matter using a suite of terahertz optics
