N-Z equation from assignment maps

Quantum Physics 2020-01-13 v2

Abstract

The Nakajima-Zwanzig(N-Z) equation is a powerful tool to analyze the open quantum system and non-Markovian behavior. In this paper, we modify the N-Z equation with assignment maps. This approach extends the application to those situations in which the bipartite state of the system and environment contains non-negligible discord initial and/or during the dynamics. We applied the equation in quantum lattice model and bound the influence of inhomogeneous terms, which figure out how the dimension of the environment impact the non-Markovian behavior.
