一种强度不等的新型两态叠加多模叠加态光场的等阶N次方Y压缩效应

本文构造了由多模虚共轭相干态{iZ_j^(a)*}>_q与多模虚共轭相干态的相反态|{-iZ_j^(b)*}>_q这两者的线性叠加所组成的一种强度不等的新型两态叠加多模叠加态光场 |Ψ^(ab)>_q.利用多模压缩态理论,对态|Ψ^(ab)>_q的等阶N次方Y压缩特性进行了详细研究.结果发现:该态在一定条件下可呈现出周期性变化的任意奇数阶和任意偶数阶的等阶N次方Y压缩效应,而在特殊条件下,则呈现出等阶N次方Y压缩简并现象.

THE PROPERTY OF GENERALIZED NONLINEAR EQUAL-ORDER N-th POWER Y-SQUEEZING IN A NEW TYPE OF UNEQUALLED-INTENSITY MULTI-MODE SUPERPOSITION STATE LIGHT FIELD WITH THE SUPERPOSITION OF MACROSCOPICALLY DISTINCT TWO QUANTUM STATE

In this paper,a new type of unequalled-intensity unsymmetric multi-mode superposition state light field |Ψ^(ab)>_q is constructed,which is made of the linear superposition of macroscopically distinct two quantum states named the multi-mode imaginary conjugate coherent state |{iZ_j^(a)*}>_q and the contrary state |{-iZ_j^(b)*}>_q of multi-mode imaginary conjugate coherent state |{iZ_j^(b)*}>_q repactively.By using the general theory of multi-mode squeezed state,the property of generaized nonlinear equal-order N-th power Y-squeezing of the state |Ψ^(ab)>_q mentioned above is studied firstly in detail.It is found that if some quantization conditions are satisfied,the state |Ψ^(ab)>_q can presents any even-order and any odd-order equal-order N-th power Y-squeezing effect that changes periodically,and if the special conditions are satisfied,the state |Ψ^(ab)>_q can always present the phenomena of equal-order N-th power Y-squeezing degenerate.
