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. She obtained a BSc in Neuroscience and a PhD in Biotechnology at Tel Aviv University\, where she worked on virus protein self-assembly in the group of Prof. Ehud Gazit.

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.
