Analysis of nonclassical behavior for a two-mode coupled-photon system

Abstract We consider a model two-mode coupled-photon system and verify that the photon distribution for this system is exactly super-Poissonian. We calculate the Glauber–Sudarshan diagonal P representation for both the individual photon subsystem and the complete photon–photon complex. We present the detailed analysis on the threshold temperature of the nonclassical behavior for the both cases. We discuss the effect of the interaction between two photons on the threshold temperature.

Generalized functional-integral approach to time evolution of a coupled photon system

A generalized functional-integral approach is presented to describe the coupled photon system in a free-electron laser. By establishing the different complex time paths to two subsystems, the Wiggler field and the laser field, an effective action of the system is introduced. A general photon distribution function is obtained by evaluating the functional integral for the generating function.
