Stochastic Schrödinger equation from an interaction with the environment
arXiv:quant-ph/9601010 · doi:10.1007/BF02085754
Abstract
We consider a class of models describing a quantum oscillator in interaction with an environment. We show that models of continuous spontaneous localization based on a stochastic Schrödinger equation can be derived as an approximation to purely deterministic Hamiltonian systems. We show an exponential decay of off-diagonal matrix elements in the energy representation.
