Hy. Fan et al., Two types of correlated binomial-negative binomial states and their nonclassical properties, MOD PHY L B, 13(29-30), 1999, pp. 1047-1054
Based on the single-mode binomial states and the negative binomial states,
we construct two types of two-mode correlated states of the quantized radia
tion field. Their nonclassical properties are investigated. It is also show
n that these states can be viewed as correlated su(2) and su(1,1) coherent
states.
