|Title:||The partial revival of the quadrature variance product in the dynamics of the squeezed vacuum field in the Jaynes-Cummings model|
|Author:||de Moura, APS|
|Abstract:||We consider the time evolution of a squeezed vacuum cavity field interacting with an initially excited tno-level atom via the Jaynes-Cummings model in the Rotating wave approximation. For large enough initial squeezing, we recognize a new partial revival phenomenon in terms of the quadrature variance product. We show the time evolution of the field quasiprobability Q-function, which provides a quadrature space picture of the partial revival phenomenon. An interpretation of the phenomenon in terms of a certain kind of first momentum of the photon distribution function is given.|
