Amiet, Jean-Pierre and Weigert, S. (2001) Contracting the Wigner kernel of a spin to the Wigner kernel of a particle. Physical Review A. art no. 012102. ISSN 1050-2947
A general relation between the Moyal formalisms for a spin and a particle is established. Once the formalism has been set up for a spin, the phase-space description of a particle is obtained from contracting the group of rotations to the oscillator group. In this process, turn into a spin Wigner kernel turns into the Wigner kernel of a particle. In fact, only one out of 22s different possible kernels for a spin shows this behavior.
