摘要
本文指出光场压缩态|α,z〉A=S(z)D(α)|0〉和|α,z〉B=D(α)S(z)|0〉不完全等价,它们实质上是本文命名的压缩子(Squeezon)湮灭算符b=SaS^+的两个本征态,具有完全相同的压缩特性,但本征值不同,光子统计分布和光子统计特性有显著差异,所含的能量状况亦很不相同。
It is shown that the squeezed states |a,s>A = S'(z)D(a) |0> and |a, s>B=D(a) S(s)|0> are not fully equivalent. In fact, they are two eigenstates of annihilation operator of squeezon called by us, as b=SaS+, with the same squeezing features but different eigenvalues. Their statistical distributions and features of photons have striking difference and the status of energies contained by them are quite different.
