SUMMARY:Photonics Initiative Seminar: Junichiro Kono
DESCRIPTION:Dr. Junichiro Kono\, Rice University\nCavity-Dressed Quantum Matter \nAbstract – There has been a growing realization that the properties of a material can be modified just by placing it in an optical cavity. The quantum vacuum fields surrounding the material inside the cavity can cause nonintuitive modifications of electronic states through ultrastrong vacuum–matter coupling\, producing a vacuum-dressed material with novel properties. Existing theoretical predictions include cavity-enhanced\, cavity-induced\, and cavity-mediated enhancement of electron–phonon coupling and superconductivity\, electron pairing\, anomalous Hall effect\, ferroelectric phase transitions\, quantum spin liquids\, and photon condensation. Achieving the so-called ultrastrong coupling (USC) regime is a prerequisite for observing these effects\, which arise when the interaction energy becomes a significant fraction of the bare photonic mode and matter excitation frequencies. Most intriguingly\, when a material is ultrastrongly coupled with cavity-enhanced vacuum electromagnetic fields\, its ground state will contain virtual photons. This nonperturbative virtual driving without external fields can lead to phase transitions in thermal equilibrium. This talk will describe our recent studies of USC phenomena in various solid-state cavity quantum electrodynamics systems in search of such vacuum-induced phases of matter. We utilize the phenomenon of Dicke cooperativity\, i.e.\, many-body enhancement of light–matter interaction\, to explore quantum-optical strategies for creating\, controlling\, and utilizing novel phases in condensed matter enabled by the quantum vacuum. \nBio – Junichiro Kono received his B.S. and M.S. degrees in applied physics from the University of Tokyo in 1990 and 1992\, respectively\, and completed his Ph.D. in physics from the State University of New York at Buffalo in 1995. He was a postdoctoral research associate at the University of California Santa Barbara from 1995-1997\, and the W. W. Hansen Experimental Physics Laboratory Fellow in the Department of Physics at Stanford University from 1997-2000. He joined the Department of Electrical and Computer Engineering of Rice University in 2000 as an Assistant Professor and was promoted to Associate Professor in 2005 and to Professor in 2009. He is currently a Professor in the Departments of Electrical & Computer Engineering\, Physics & Astronomy\, and Materials Science & Nanoengineering at Rice University. \n\nProfessor Kono has also founded and implemented multiple education programs\, including the nationally recognized international research experience program called NanoJapan. NanoJapan was funded by the U.S. National Science Foundation and received the Heiskell Award for Innovation from the Institute of International Education in 2008. In 2016\, his team was selected by the U.S.-Japan Council to implement TOMODACHI STEM @ Rice\, which serve as a catalyst for female Japanese students interested in science and engineering research and engagement with the U.S. through international research collaborations. Professor Kono is a leader in optical studies of condensed matter systems and photonic applications of nanosystems\, including semiconductor nanostructures and carbon-based nanomaterials. He has made a number of pioneering contributions to the diverse fields of semiconductor optics\, terahertz spectroscopy and devices\, ultrafast and quantum optics\, and condensed matter physics. \nSpecifically\, his high-impact achievements include: exploration of extreme nonlinear optics in semiconductors using small-energy photons; ultrafast optical manipulation of collective spins in ferromagnetic semiconductors; observation of the Aharonov-Bohm effect in carbon nanotubes via magneto-optics; ultrafast and nonlinear optical studies of carbon nanotubes; first observation of superfluorescence in a solid through cooperative recombination of quantum degenerate electron-hole pairs; and demonstrations of the ultrastrong coupling regime in high-Q terahertz cavities. Kono’s research group uses state-of-the-art spectroscopic techniques to probe charge\, spin\, and vibrational dynamics. Their experimental facilities include the RAMBO system — a unique mini-coil-based 30-T pulsed magnet system equipped with ultrafast and nonlinear optical spectroscopy setups.

SUMMARY:Photonics Initiative Seminar: Maria Antonietta Loi
DESCRIPTION:Dr. Maria Antonietta Loi\, University of Groningen \nCOLLOIDAL QUANTUM DOT SUPERLATTICES: TOWARDS OPTOELETRONIC METAMATERIALS \nAbstract – 3D superlattices made of colloidal quantum dots are a promising candidate for the next generation of optoelectronic devices as they are expected to exhibit a unique combination of tunable optical properties and coherent electrical transport through minibands. In my presentation I will show the fabrication of 3D superlattices of PbSe and PbS QDs with nanoscale-level controlled ordering over large areas [1\, 2]\, and of outstanding transport properties. The measured electron mobilities for PbSe superlattices are the highest ever reported for a self-assembled solid of fully quantum-confined objects (electron mobility up to 278 cm2 V−1 s−1). This ultimately demonstrates that optoelectronic metamaterials with highly tunable optical properties (in this case in the short-wavelength infrared spectral range) and charge mobilities approaching that of bulk semiconductor can be obtained. This finding paves the way toward a new generation of optoelectronic devices. \nReferences:  \n[1] J. Pinna\, R. Mehrabi Koushki\, D. S. Gavhane\, M. Ahmadi\, S. Mutalik\, M. Zohaib\, L.
