Electric field in the coherent-state Jaynes-Cummings model
Philip Goldberg, Lee C. Harrison · Physical Review A · 1991
A complete description of the electric field in the Jaynes-Cummings model is presented using the exact operator solutions for the field variables. Two-time field correlation functions are calculated which display the destruction and subsequent partial revival of field coherence. It is shown that squeezing of the field can be enhanced for small n\ifmmode\bar\else\textasciimacron\fi{} when the atom is initially in a coherent superposition state. Amplitude-squared squeezing of both field quadratures occurs for all values of n\ifmmode\bar\else\textasciimacron\fi{} with these initial conditions. The squeezing is not related to collapse and revival phenomena.
