Quantum interference induced by initial system–environment correlations / Z.X. Man, A. Smirne, Y.J. Xiaa, B. Vacchini. - In: PHYSICS LETTERS A. - ISSN 0375-9601. - 376:36(2012), pp. 2477-2483.
Abstract:
We investigate the quantum interference induced by a relative phase in the correlated initial state of a system which consists in a two-level atom interacting with a damped mode of the radiation field. We show that the initial relative phase has significant effects on both the evolution of the atomic excited-state population and the information flow between the atom and the reservoir, as quantified by the trace distance. Furthermore, by considering two two-level atoms interacting with a common damped mode of the radiation field, we highlight how initial relative phases can affect the subsequent entanglement dynamics.
