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.
