Lindblad Superoperators from Wigner's Phase Space Continuity Equation
Ole Steuernagel, Ray-Kuang Lee
For a simple quantum system weakly interacting with the environment Wigner's 1932 formulation of quantum physics can be used to derive coupling to the environment using simple alge…

Wigner's Phase Space Current for Variable Beam Splitters -Seeing Beam Splitters in a New Light-
Ole Steuernagel, Ray-Kuang Lee
Beam splitters allow us to superpose two continuous single mode quantum systems. To study the behaviour of their strongly mode mixing dynamics we consider variable beam splitters a…
