VARIATION FROM NUMBER-STATE TO CHAOTIC-STATE FIELDS - A GENERALIZED GEOMETRIC STATE

We introduce a formal state of the radiation field which interpolates between the (pure) number (Fock) state and the (nonpure) chaotic state . The correlation functions and the squeezing properties are studied. The study of two quantum optical systems (namely, the Jaynes-Cummings model and resonance fluorescence for a single atom and many cooperativ e atoms) in such a state of the radiation field provides more insight into the gradual behavior as one goes from the number state to the cha otic state. A scheme for the production of such a state is sought to b e realized in a model of multiphoton processes in a finite-level atomi c system. The quasiprobability Wigner distribution function for such a state is also examined.
