The perturbation to non-Markovian equation of motion corresponding to coherent and quadrature non-Markovian SSES

Abstract

In this paper, we derive the perturbation and post Markovian perturbation to non-Markovian equation of motion(NMEM) that correspond to coherent and quadrature non-Markovian stochastic Schr¨odinger equations (SSE). In that case, we derive two perturbation approaches for zero and first orders to the coherent and quadrature NMEM. In order to explain both approaches, we apply two examples of non-Markovian.
