Resumo
We introduce new two-parameter states of the quantized radiation field
interpolating from number states to chaotic states. Instead of dealing with
pure states, we consider truncated mixtures of number
states—number-chaotic states (NCS)—which reduce to number and chaotic
(thermal) states in two well-defined limits. We study the statistical and
squeezing properties of such states and show that there is a value of the
chaoticity parameter ¯n at which a transition from sub- to super-Poissonian
characteristics occurs. Analysing the atomic population inversion in the
Jaynes–Cummings model for these NCSs, we demonstrate the appearance
of collapses and revivals as ¯n is increased. Their phase space representations
are studied emphasizing the changes as the parameters are varied and we
discuss the nonclassical depth.
