| 摘 要： | 通过数值计算研究了激发双模压缩真空态a+mb+m|ξ>的非经典特性.结果表明:对于a+mb+m|ξ>,Cauchy-Schwartz不等式受到破坏;当取适当的压缩参量r(例如0.4～0.7)时,a+mb+m|ξ>呈现出正交分量的压缩和光子的亚泊松分布,而且压缩程度和亚泊松特性都随m的增大而有所增强.

| Abstract: | The excited two mode squeezed vacuum state a+m b+m |ξ> is studied.It is shown that when the squeeze parameter r is chosen reasonably the state a+m b+m |ξ> exhibits interesting nonclassical properties such as violation of the Cauchy Schwartz inequality,two-mode squeezing and sub-Poissonian statistics of the field,and as m increases,the squeezing and the sub Poissonian character increase. |

| Keywords: | Two mode squeezed vacuum state Excited two mode squeezed vacuum state Nonclassical properties |
