Semiclassical propagator of the Wigner function
Thomas Dittrich, Luis Sandoval, Carlos Viviescas
Propagation of the Wigner function is studied on two levels of semiclassical propagation, one based on the van-Vleck propagator, the other on phase-space path integration. Leading…

Wigner function for discrete phase space: exorcising ghost images
Arturo Argüelles, Thomas Dittrich
We construct, using simple geometrical arguments, a Wigner function defined on a discrete phase space of arbitrary integer Hilbert-space dimension that is free of redundancies. ``G…
