Entangled coherent states in symmetry phase spaceand their nonclassical effects

Abstract

We discuss the entangled coherent states in symmetry phase space by introducing orthogonal basis, calculate their entanglement by means of concurrence, and investigate their squeezing effects of single-mode and two-mode and antibunching effects. The calculations indicate that the entangled coherent state in symmetry phase space is closely related to nonclassical effect.
