Abstract

Theoretical calculations show that the generalized odd and even coherent states(OECS) of a non harmonic oscillator represent higher power (odd number power) squeezing effect and antibunching effect respectively, and these photon statistical characteristics are very different from those of the ordinary OECS.

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.

HIGHER POWER SQUEEZING EFFECTS FOR ODD AND EVEN q-COHERENT STATES

WANG ZHONG-QING, 石油大学应用物理系,东营257061

The higher power squeezing effects of photon field for odd and even q coherent states have been studied. We find that the squeezing effects are influenced by the values of parameter q, and the odd and even q-deformed coherent states can exhibit odd power squeezing effect but no even power squeezing effect when parameter q is taken values departure from 1 greatly, and these squeezing characteristics are different from those of the conventional odd and even coherent states.

The Properties of Generalized Even and Odd Coherent States of a q-Deformation Non-harmonic Oscillator

Hong‐Mei Zou

The generalized even and odd coherent states of a q-Deformation Non-harmonic Oscillator(E-O q-NHCSs) are constructed,their Higher-Order Squeezing and Antibunching Properties are studied in detail.It is increasing the Squeezing effect in different parameter ranges.With q-deformation increasing,the squeezing effect of E q-NHCSs are weakened and those of O q-NHCSs are enhanced.The E q-NHCSs appear high-order(N≥2) antibunching properties while the O q-NHCSs appear high-order bunching properties in some ranges of the parameter q and r 2 with the q-deformation increasing.Both antibunching effects of E q-NHCSs and bunching effects of O q-NHCSs are enhanced.

EVEN AND ODD GENERALIZED COHERENT STATES IN THE NON HARMONIC OSCILLATOR POTENTIAL

XU ZI-WEN, 北京机械工业学院基础部

In this paper,the conception of even and odd coherent states is generalized to the nonharmonic oscillator potential. It is found that squeezing exists alternatively in the even and odd coherent states with the increase of the mean energy, and the squeezing of the quantum fluctuation of the natural coordinate in the time evolution has a period of π/2.
