The Wigner flow on the sphere
P. Yang, I. F. Valtierra, A. B. Klimov +4
We derive a continuity equation for the evolution of the SU(2) Wigner function under nonlinear Kerr evolution. We give explicit expressions for the resulting quantum Wigner current…

Phase space representation of non-Hermitian system with -symmetry
Ludmila Praxmeyer, Popo Yang, Ray-Kuang Lee
We present a phase space study of non-Hermitian Hamiltonian with -symmetry based on the Wigner distribution function. For an arbitrary complex potential, we derive a…
