Hazards of reservoir memory

Barnett, S.M. and Stenholm, S.T. (2001) Hazards of reservoir memory. Physical Review A, 64 (3). 033808. (https://doi.org/10.1103/PhysRevA.64.033808)

Abstract

We add memory effects to the master equation describing a harmonic oscillator embedded in a reservoir. Solving the time evolution exactly, we show that the model is sensible only in the Markovian limit. Thus we issue a warning against indiscriminate introduction of memory effects in master equations and call for a systematic method to obtain corrections to Markovian time evolution.
