Description
Summary:Two forms of dissipation are applied to a system of two coupled harmonic oscillators. Result¬ing quantum master equations are studied with the help of quantum characteristic functions. The effects of dissipation on quantum entanglement are investigated in the view of recent interest in separability criteria for density matrices. Decoherence-free subspaces are constructed for a Lindlad dissipation mechanism.
