Squeezing in the Real and Imaginary Spin Coherent States
Dong Yan, Xiaoguang Wang, Ling-An Wu · Chinese Physics Letters · 2005
We study spin squeezing properties in the real and imaginary spin coherent states. We obtain analytical expressions of two spin squeezing parameters via a novel ladder operator formalism of the spin coherent state and the generation function method. Numerical results of the spin squeezing properties are discussed in detail, and the real and imaginary spin coherent state can be spin squeezed over a large range of parameters.
