Geometric approach to non-relativistic quantum dynamics of mixed states
AIP Publishing LLC (2013-05)In this paper we propose a geometrization of the non-relativistic quantum mechanics for mixed states. Our geometric approach makes use of the Uhlmann's principal fibre bundle to describe the space of mixed states and as a ... -
Upper bounds for the Poincaré recurrence time in quantum mixed states
IOP Publishing Ltd. (2017-04)In this paper we use geometric techniques to provide upper bounds for the Poincaré recurrence time of a quantum mixed state with a discrete spectrum of energies. We obtain two types of upper bounds. One of them depends on ...
