摘要
根据量子力学中的线性叠加原理，构造了由多模真空态 和多模虚相干态 这两者的线性叠加所组成的第Ⅸ类两态加多模叠加态光场 利用多模压缩态理论，对态 的 广义非线性Ｎ次方Ｙ压缩特性进行了详细研究．结果发现：（１）、无论压缩次数Ｎ取奇还是取偶，只 要各模的初始相位(ｊ＝１，２，３，…ｑ）和态间的初始相位差（ ）分别满足一定的量子优化条 件，态 的第一和第二这两个正交分量总可分别呈现出周期性变化的任意奇数次和任意偶 数次的广义非线性Ｎ次方Ｙ压缩效应；（２）、本文所构造的态 与文献[１１］构造的态 ， 两者在一定条件下可分别呈现出“Ｎ次方Ｙ相似压缩”和“Ｎ次方Ｙ压缩简并”现象．
According to the Linear superpositon principle in quantum mechanics ,the ninth kind of two ligtht Field is constructed that is composed of multimode vaccum state light field And then the multimode squeezed state theory suggested by Yang Zhiyong and Hou Xun and Published in Acta Photonica Sinica is utlized to study the properties of generalized nonlinear equal- power N-th power Y-squeeting of the state mentioned above. It is found that ①、whether the squeezing-power-number N is an odd-number or an even-number, while some certain quantization conditions are satisfied by the initial phase of each mode and by the initial phase difference( ) between two components of the state respectively ,the state can always present any odd-number power any even-number N-th power Y-squeezing effects which changes periodically. ② Compared with the reference [11] ,the state constructed in this paper is rathier different from the state constructed in reference [11] ,under some fixed conditions the states and can display the phenomena of N-th power Y-similitude- squeezing and N-th power Y-degenerate-squeezing.
