Séminaire du LPTMS: Eric Akkermans

Topology and fractals : waves and fields in quasicrystals (theory and experiments with polaritons)

Eric Akkermans, Technion – Israel Institute of Technology

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.
