Wigner distribution of a general angular-momentum state: Applications to a collection of two-level atoms. Academic Article uri icon

abstract

  • 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(,cphi) are represented as a pseudoprobability distribution in spherical phase space with spherical coordinates and cphi on the surface of a sphere of radius Latin small letter h with stroke j(j+1) where j is the total angular-momentum eigenvalue. 1994 The American Physical Society.
