Geometric phases in open systems: A model to study how they are corrected by decoherence
Geometric phases in open systems: A model to study how they are corrected by decoherence
We calculate the geometric phase for an open system (spin-boson model) which interacts with an environment (ohmic or nonohmic) at arbitrary temperature. However there have been many assumptions about the time scale at which the geometric phase can be measured, there has been no reported observation of geometric phases for …
