Lecturer: Prof. Eric Akkermans Affiliation: Technion Abstract: I will present recent results obtained both theoretically and experimentally on fractal spectral properties of a polariton gas in a Fibonacci quasi-periodic potential. The observed spectrum is accurately reproduced from a theoretical model that we shall present. We have observed for the first time log- periodic oscillations and the opening of mini- gaps following the gap labeling theorem. These results illustrate the potential of cavity polaritons as a quantum simulator in complex topological geometries. ‏האירוע הזה כולל שיחת וידאו ב-Google Hangouts. הצטרף: https://hangouts.google.com/hangouts/_/mail.huji.ac.il/condensed?hceid=b...
