Title: A generalized Wigner function for quantum systems with the SU(2) dynamical symmetry group
Author: Klimov, Andrei B.

Issue Date: 2008
Abstract: We introduce a Wigner-like quasidistribution function to describe quantum systems with the SU(2) dynamic symmetry group. This function is defined in a three-dimensional group manifold and can be used to represent the states defined in several SU(2) invariant subspaces. The explicit differential Moyal-like form of the star product is found and analyzed in the semiclassical limit. � 2008 IOP Publishing Ltd.
