Pólya states of quantized radiation fields, their algebraic characterization and non-classical properties
Hong-Chen Fu · Journal of Physics A Mathematical and General · 1997
Pólya states of a single-mode radiation field are proposed and their algebraic characterization and non-classical properties are investigated. They degenerate to the binomial (atomic coherent) and negative binomial (Perelomov's su(1,1) coherent) states in two different limits and further to the number, the ordinary coherent and Susskind - Glogower phase states. The algebra involved turns out to be a two-parameter deformation of both su(2) and su(1,1). Non-classical properties are investigated in detail.
