有限维空间谐振子压缩态及压缩特性

Squeezed States of a Hamonic Oscillator in a Finite Dimensional Hilbert Space and Their Squeezing Properties

构造了有限维Ｆｏｃｋ空间的压缩态，详细地研究了压缩态中一对正交算符的压缩性质．结果表明，正交算符在这种有限维Ｆｏｃｋ空间压缩态中具有压缩效应；

Squeezed states of a harmonic oscillator in a finite dimensional Fock space are constitued in this article.The second order squeezing of these squeezed states with respect to the quadrature operators is studied in detail.It is shown that these squeezed states exhibit squeezing effects.And when the dimension s→∞,the squeezed states in a finite dimensional Fock space is namely the usual squeezed states in an infinite dimensional Fock space.
