The quantum properties of the atom in the nonlinear interaction between squeezing vacuum state field and atom
Huang Yan-xia, Zhao Peng-Yi
Abstract
The properties of the atomic inversion and the atomic state evolution in the intensity-dependent coupling interaction between squeezing vacuum state field and atom with an additional kerr medium are investigated by using the distance between density operators. The influences of nonlinear interaction intensity of kerr medium and the squeezing degree of initial squeezing vacuum state field on the quantum properties of the atom are discussed.
