Asymptotic entanglement and Lindblad dynamics: a perturbative approach
Fabio Benatti, A Nagy, H Narnhofer · Journal of Physics A Mathematical and Theoretical · 2011
We consider an open bipartite quantum system with dissipative Lindblad type dynamics. In order to study the entanglement of the stationary states, we develop a perturbative approach and apply it to the physically significant case when a purely dissipative perturbation is added to the unperturbed generator which by itself would produce reversible unitary dynamics.
