Quantum Information Aspects of Cold Fermi Systems

In the limit of fast switching of Feshbach resonance in cold fermionic systems, the dynamics is dominated by non-linear, coherent, multi-frequency quantum oscillations of the order parameter. This theoretical model is very rich and has known connections to several quantum field theories. In this talk, I will analyze the problem from the point of view of quantum information theory and indicate possible practical applications of the fast-switching regime.
