光子湮没算符高次幂本征态的压缩性质

SQUEEZING PROPERTIES OF EIGENSTATES OF HIGH ORDER POWER OF PHOTON ANNIHILATION OPERATOR

本文研究光子湮没算符高次幂α~k(k≥3)的k个正交归一本征态的压缩性质,发现当k为偶数时,这些本征态均可有振幅N次方(k=2N)压缩存在。

In this paper, the squeezing properties of orthonormal eigenstates of high order power of photon annihilation operator ak (k≥3) are studied. It is shown that the amplitude Nth-power squeezing (k=2N) can exist in the eigenstates when k is even.
