| Abstract: | By using the technique of integration within an ordered product (IWOP) of
operator we derive Wigner function of density operator for negative binomial
distribution of radiation field in the mixed state case, then we derive the
Wigner function of squeezed number state, which yields negative binomial
distribution by virtue of the entangled state representation and the
entangled Wigner operator. |
