Lecturer: Prof. Alex Hayat Affiliation: Department of Electrical Engineering, Israel Institute of Technology - Technion Abstract: Interest in the superconducting proximity effect has been reinvigorated recently by novel optoelectronic applications as well as by the possible emergence of the elusive Majorana fermion. We produced high- temperature proximity-induced superconductivity in topological insulators, using our new mechanical bonding technique. We demonstrated hybrid high- Tc-superconductor-semiconductor tunnel junctions with bulk semiconductors and with semiconductor quantum wells. We showed theoretically that superconductor- semiconductor devices can produce entangled photon pairs when a proximity layer is induced in semiconductor nanostructures. Exciton-polaritons that emerge from strong coupling of photons to excitons in semiconductor microcavities have an extremely small effective mass, and can therefore condense at very high temperatures. We demonstrated temporal long-range off-diagonal order in dynamic polariton condensates with large nonlinear phase shifts. We showed a dynamic Stark shift of exciton-polaritons which provides a fast-switching technique for ultrafast circuits, for generation of optical lattices, and for quantum tomography on polariton condensates. ‏האירוע הזה כולל שיחת וידאו ב-Google Hangouts. הצטרף: https://hangouts.google.com/hangouts/_/mail.huji.ac.il/condensed?hceid=b...
