Gaussian Approximation of the Wigner Function for the Stochastic Schrödinger Equation — •Robson Christie, Jessica Eastman, and Eva-Maria Graefe — Imperial College London, UK

Stochastic Schrödinger equations arise in many contexts in quantum mechanics, for example as an unravelling of the Lindblad equation. Here the time evolution of the Wigner function of a Gaussian state evolving along a trajectory of the stochastic Schrödinger equation for arbitrary Lindbladians is investigated in the semiclassical limit. The resulting coupled stochastic differential equations are compared to the full quantum dynamics for example systems.
