Interplay of different environments in open quantum systems: Breakdown of the additive approximation

Giusteri, Giulio G. ; Recrosi, Filippo ; Schaller, Gernot ; Celardo, G. Luca (2017)

We analyze an open quantum system under the influence of more than one environment: a dephasing bath and a probability-absorbing bath that represents a decay channel, as encountered in many models of quantum networks. In our case, dephasing is modeled by random fluctuations of the site energies, while the absorbing bath is modeled with an external lead attached to the system. We analyze under w...
