Abstract
We discuss generic spin squeezing operators (quadratic in angular momentum operators) capable of squeezing out quantum mechanical noise from a system of two-level atoms (spins) in a coherent state. Such systems have been considered by Kitagawa and Ueda (Refs. 2) in this context and a Hamiltonian of this nature governs the Lipkin model (Ref. 14) which is relevant to nuclear physics.
