Project

Transport and stability in periodically driven systems with applications to the quantum Hall effect. (MEB021012)

A study of the dynamics of periodically driven quantum systems. The goals are to prove the existence of a charge transport for systems driven by a periodically time-dependent Aharonov-Bohm flux in the resonant case, and to derive sufficient ...
