Single-Particle Coherence and Spin Squeezing in Two-Particle Phase State

We investigate the relation between the single-particle coherence and spin squeezing in two-particle phase state governed by an one-axis twisting Hamiltonian. The single-particle coherence and spin squeezing parameter only depends on the nonlinear interaction, and they have the same period of oscill...

Description
Summary:We investigate the relation between the single-particle coherence and spin squeezing in two-particle phase state governed by an one-axis twisting Hamiltonian. The single-particle coherence and spin squeezing parameter only depends on the nonlinear interaction, and they have the same period of oscillation and the maximum and the minimum.
