Critical Behaviour and Optical Bistability of the Tavis-Cummings Model in a Driven Low-Q Cavity
R. Bullough, Saad S. M. Hassan, Ravinder Rupchand Puri · 1985
The Tavis-Cummings model1 is one of the few exactly solvable quantum models in nonlinear optics: it consists of N > 1 2-level atoms interacting with a single mode of the quantised radiation field. The N atoms occupy a single site as in the Dicke model2; but there is no coupling to other modes of the field and no conventional radiation damping. Since the single mode is quantised in a cavity of finite volume this can be thought of as a physical cavity of infinite Q.
