Field-induced dynamics in the quantum Brownian oscillator: An exact treatment
arXiv:1002.2772 · doi:10.1016/j.physleta.2010.07.051
Abstract
We consider a quantum linear oscillator coupled to a bath in equilibrium at an arbitrary temperature and then exposed to an external field arbitrary in form and strength. We then derive the reduced density operator in closed form of the coupled oscillator in a non-equilibrium state at an arbitrary time.
