    • Wigner functions and coherent states for the quantum mechanics on a circle 

      Kowalski, Krzysztof ORCID; Ławniczak, Karol ORCID (IOP Publishing, 2021)
      The Wigner functions for the coherent states of a particle on a circle are discussed. The nontrivial analytic forms of these functions are derived. The classicality of the circular coherent states existing in the literature ...
