文摘Even coherent states (ECSs) of a finite-dimensional Hilbert space harmonic oscillator (FDHSHO) are constructed explicitly.Some properties of them are discussed.The quadrature squeezing and the amplituded-squared squeezing of these states are investigated in detail.It is found that ECSs of the FDHSHO exhibit not only the quadrature squeezing but also the amplituded-squeezing.
