混合迭加态的振幅N次方压缩

THE NTH-POWER SQUEEZING OF FIELD AMPLITUDE IN MIXED SUPERPOSITION STATES

本文讨论了由粒子数态组成的混合迭加态产生振幅N次方压缩的条件,导出了求取所有能产生振幅N次方压缩的混合迭加态以及它们的压缩条件的一般公式。

The conditions of the Nth-Power squeezing of the field amplitude in mixed superposition states ψ(m,n) are investigated. We find that only when n-m=N or n-m - 2N, the states ψ(m.n) can exhibit the squeezing. Using the method in this paper, we cut obtain all the states ψ(m,n) in which the squeezing can occur and the conditions of the squeezing in these states.
