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 ...
