Phys. Rev. A 49, 4101–4109 (1994)Wigner distribution of a general angular-momentum state: Applications to a collection of two-level atomsReceived 10 November 1993; published in the issue dated May 1994 The general theory of quantum angular momentum is used to derive the unique Wigner distribution function for arbitrary angular-momentum states. We give the explicit distribution for atomic angular-momentum Dicke states, coherent states, and squeezed states that correspond to a collection of N two-level atoms. These Wigner functions W(θ,cphi) are represented as a pseudoprobability distribution in spherical phase space with spherical coordinates θ and cphi on the surface of a sphere of radius ħ √j(j+1) where j is the total angular-momentum eigenvalue. © 1994 The American Physical Society URL:
