Abstract:

In this talk, first, two possible experimental schemes for ultracold fermionic atoms inside cavities will be presented. The first one is to measure the antiferromagnetism correlations in the two-dimensional Hubbard model; via the cavity-induced Bragg scattering of an off-resonant laser, which is amplified significantly by the cavity. The other scheme aims for the generation of a disordered optical lattice potential with cavities. Next I will talk about the technique part, which describes the frequency stabilization of external-cavity diode lasers with a high-finesse optical cavity by the Pound Drever Hall technique, as well as phase lock of optical fibers.

Coffee and cake will be served from 12:05
