Dynamics and non-equilibrium steady state in a system of coupled harmonic oscillators
arXiv:1402.1477 · doi:10.1016/j.physleta.2013.04.001
Abstract
A system of two coupled oscillators, each of them coupled to an independent reservoir, is analysed. The analytical solution of the non-rotating wave master equation is obtained in the high-temperature and weak coupling limits. No thermal entanglement is found in the high-temperature limit. In the weak coupling limit the system converges to an entangled non-equilibrium steady state. A critical temperature for the appearance of quantum correlations is found.
