Peremolv SU(1,1)相干叠加态的二阶量子关联特性研究

PERELOMOV SU (1,1) COHERENT SUPERPOSITION STATES

本文首先讨论了Barut－GirardelloSU（1，1）相干叠加态在Bargmann指数k≠1／2时的二阶量子关联特性．发现随着Bargmann指数的增大，Barut－Girardello奇相干态呈现反关联的区域变大．然后提出并研究了PeremolovSU（1，1）相干叠加态．Peremolov奇相干态可呈现反关联，并且随着Bargmann指数的增加，反关联程度变弱，反关联区域变小．

It is studied the second-order correlation of Barut-Girardello SU (1, 1 ) coherentsuperposition states with large Bargmann index and found that the odd coherent state can show anticorrelation region becomes wide when Bargman index increases. Then,in parallel to Barut-Girardellocoherent superposition states, it is introduced Peremolov coherent superposition states and studiedtheir second-order correlation. The Peremolov odd coherent states can exhibit anti-correlation. WhenBargmann index increases,the range of anti-correlation becomes narrow and the degree is reduced.
