Relaxation, thermalization, and Markovian dynamics of two spins coupled to a spin bath

Abstract

It is shown that by fitting a Markovian quantum master equation to the numerical solution of the time-dependent Schrodinger equation of a system of two spin-1/2 particles interacting with a bath of up to 34 spin-1/2 particles, the former can describe the dynamics of the two-spin system rather well. The fitting procedure that yields this Markovian quantum master equation accounts for all non-Markovian effects in as much the general structure of this equation allows and yields a description that is incompatible with the Lindblad equation.</p
