摘　　要：构造了非简谐振子湮没算符高次幂本征态的叠加态｜ψj(β)>+ei｜ψj(βeiδ)>,并研究了它的高阶压缩效应和反聚束效应,结果表明参数相位差对它的高阶压缩阶数和反聚来效应起决定性作用。The superposition of the eigenstates of the Nth powers(N≥3)of the annihilation operator of the non-harmonic oscillator is constructed.Its higher-order squeezing effect and antibunching effect are studied.The results show that the order of squeezing and antibunching effect are determined by the phase difference.
