Numerical Studies on the Nonclassical Properties of Odd Co herent States in a Finite-Dimensional Hilbert Space q-Deformation Harmonic Os cillator

Abstract

The influences of q deformation on the nonclassi cal properties of odd q-coherent states in a finite-dimensional Hibert spaces ( FDHS ) case are studied by numerical method. It is found that, while q1, the s queezing effect appears and antibunching effect disappears in some range of r-2. With q deformation increasing, the squeezing degree is stren gthened and the antibunching effect is weakened.

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.

Quantum Statistical Properties of Even and Odd qs -Coherent States

Wang Jisuo, Sun Chang-yong

In this paper, we use the numerical method to study the influences of and deformations on the quantum statistical properties of even and odd qs-coherent states. It is shown that nonclassical properties of the even and odd qs-coherent states are very different from those of the usual even and odd coherent states. It is found that squeezing and antibunching effect appear for both even and odd qs-coherent states in some range of the parameters , and . The smaller the and are, the larger the difference between the even and odd qs-coherent states and the usual even and odd coherent states is.

It is found that squeezing effect appears for both even and odd q-CSs and has quasiperiodicity, and the antibunching effect may appear for even q-CSs but disappear for odd q-CSs in some range of the parameters q and r. 作者及机构信息 朱从旭2, 王发伯1, 匡乐满1 (1)湖南师范大学物理系,高等科学技术中心(世界实验室); (2)中南工业大学研究生处 Authors and contacts ZHU CONG-XU2, WANG FA-BO1, KUANG LE-MAN1 (1)湖南师范大学物理系,高等科学技术中心(世界实验室); (2)中南工业大学研究生处 参考文献 施引文献
