Higher-Order Squeezing and Antibunching Effect for the Odd and Even Generalized q-Coherent States of the Non-harmonic Oscillator

Zhong Wang

The higher order squeezing and antibunching effect for the odd and even generalized q coherent states of the non harmonic oscillator are investigated. The numerical method is used to study these effects for the two expressions of q number . It is shown that the odd and even generalized q coherent states of the non harmonic oscillator present higher order (order of odd number) squeezing effect and antibunching effect respectively,and these optical statistics properties are very different from those of the states of the harmonic oscillator.

Superposition of Generalized q-Coherent States of the Non-harmonicOscillator and Their Nonclassical Properties

Zhongqing Wang, Zhou Qing Ping, Zhu Lianxuan +1 more

The superposition states, which are composed of the generalized q-coherent states of the non-harmonic oscillator, are presented. The quantum statistical properties of these states are studied. Then the influence of the superposition phase δ and the deformation parameter q on these nonclassical properties are discussed. It is shown that the superposition states exhibit higher-order (order of odd number) squeezing effect and antibunching effect respectively. When the superposition phase δ is taken values approach to 0 or π/2, these results approach the properties of the even or odd generalized q-coherent states of the non-harmonic oscillator. Especially, the effects are influenced by the parameter q. When the values of q is taken departure from 1 greatly, the nonclassical properties are more evidently.
