Wigner function for the orientation state — •Timo Fischer1, Clemens Gneiting2, and Klaus Hornberger1 — 1Fakultät für Physik, Universität Duisburg-Essen, 47057 — 2Institut für Physik, Albrecht-Ludwigs Universität Freiburg, 79104
A new quantum phase space representation for the rotational degrees of freedom will be presented, which is closely analogous to the Wigner-Weyl formalism for the Cartesian case. We discuss the explicit form of the Wigner function and the basic Weyl symbols, as well as the associated quantum Liouville equation. For macroscopically extended states the latter turns into the classical Liouville equation up to quantum corrections.
