Trace forms for the generalized Wigner functions

量子物理 2016-09-08 v1

摘要

We derive simple formulas connecting the generalized Wigner functions for ss-ordering with the density matrix, and vice-versa. These formulas proved very useful for quantum mechanical applications, as, for example, for connecting master equations with Fokker-Planck equations, or for evaluating the quantum state from Monte Carlo simulations of Fokker-Planck equations, and finally for studying positivity of the generalized Wigner functions in the complex plane.
