The Wigner Kernel of a Particle obtained from the Wigner Kernel of a Spin by Group Theoretical Contraction
Jean-Pierre Amiet, Stefan Weigert
The Moyal formalism for a particle can be derived from the Moyal formalism for a spin. This is done by contracting the group of rotations to the oscillator group. A new derivation…

Contracting the Wigner-Kernel of a Spin to the Wigner-Kernel of a Particle
Jean-Pierre Amiet, Stefan Weigert
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 i…
