Non-linear Higher-order Squeezing Effects for the Pair Coherent State
Jiang Jun-qin · 2005
In this paper, the non-linear higher-order squeezing effects of photon field for the pair coherent state |=A_0n=0~nn!|n,n are studied. It is shown that the photon field can exhibit the equal-order N-th power Y-squeezing effects (N=2,3,4,5,) but cannot exhibit the equal-order N-th power H-squeezing effects, the pair coherent state is N-H minimum uncertainty state.
