Inhomogeneous quantum diffusion and decay of a meta-stable state
arXiv:cond-mat/0608269 · doi:10.1016/j.physleta.2006.08.014
Abstract
We consider the quantum stochastic dynamics of a system whose interaction with the reservoir is considered to be linear in bath co-ordinates but nonlinear in system co-ordinates. The role of the space-dependent friction and diffusion has been examined in the decay rate of a particle from a meta-stable well. We show how the decay rate can be hindered by inhomogeneous dissipation due nonlinear system-bath coupling strength.
