Abstract: | In the paper we examine some properties of the generalized coherent states of the Barut-Girardello kind. These states are
defined as eigenstates of a generalized lowering operator and they are strongly dependent on the structure constants. Besides
the pure coherent states we focused our attention on the mixed states one, which are characterized by different probability
distributions. As some examples we consider the thermal canonical distribution and the Poisson distribution functions. We
calculate for these cases the Husimi’s Q and quasi-probability P-distribution functions. |
