摘要
本文研究了光子消灭算符三次幂a^3正交归一本征态的高阶压缩。结果表明,a^3的三个正交归一本征态都没有Zhang等人定义的高阶压缩,但它们都是算符Z_1(N)和Z_2(N)(N=3m,m=1,2,…)的最小测不准态,从而推广了其他作者的结果。
The higher--order squeezing of the orthonormalized eigenstates of the cubic powera^3 of the annihilation operator are studied in this paper. The results show that noneof the three orthonormalized eigenstates of a^3 have the higher--order squeezing de-fined by Zhang et al.and all of them are the minimum uncertainty states of theoperators Z_1 (N)and Z_2 (N) (N=3m; m=1,2,……).Therefore we have generalized theresult given by other authors.
