Aharonov-Anandan phase and the quasistationarity of driven quantum systems — •Alex Matos-Abiague and Jamal Berakdar — Max-Planck Institut für Mikrostrukturphysik,

We derive necessary and sufficient conditions for the quasistationarity of a time-dependent quantum system and point out the relationship between the degree of quasistationarity, the Fubini-Study metric, and the Aharonov-Anandan geometric phase. As an illustration we analyze the dynamical localization of an electron in a double quantum well as well as the sustainability of field-induced orientation of polar molecules.
