New approach for Damping in a squeezed bath and its time evolution through Complete Class of Gaussian Quasi-distributions (1402.2545v1)
Published 11 Feb 2014 in quant-ph
Abstract: By virtue of the thermal entangled states representation of density operator and using dissipative interaction picture we solve the master equation of a driven damped harmonic oscillator in a squeezed bath. We show that the essential part of the dynamics can be expressed by the convolution of initial Wigner function with a special kind of normalized Gaussian in phase space and relate the dynamics with the change of Gaussian ordering of density operator.
