Quantum phase-space representation for curved configuration spaces
Clemens Gneiting, Timo Fischer, Klaus Hornberger
We extend the Wigner-Weyl-Moyal phase-space formulation of quantum mechanics to general curved configuration spaces. The underlying phase space is based on the chosen coordinates o…

Wigner function for the orientation state
Timo Fischer, Clemens Gneiting, Klaus Hornberger
We introduce a quantum phase space representation for the orientation state of extended quantum objects, using the Euler angles and their conjugate momenta as phase space coordinat…
