Abstract

Description

Mixed states of samples of spin s particles which are symmetric under permutations of the particles are described in terms of their total collective spin quantum numbers. We use this description to analyze the influence on spin squeezing due to imperfect initial state preparation.
Section V on extension of the results to atoms with more than two levels has been rewritten. Accepted for publication in Phys. Rev. A
