Abstract: (3428 Views)
In this paper, we study the interaction of two identical Λ-type three-level atoms with a pair of coherent field in the presence of converter terms (coupled fields). Indeed, in addition to the interaction between the atoms and fields, the fields are interacting with each other, too. By applying the appropriate canonical transformations, the introduced model is reduced to a well-known form of the generalized Jaynes-Cummings model for the interaction between two three-level atoms and two coupled modes. After obtaining the explicit form of the atom-field wave function by using the Laplace transform technique, in order examine the nonclassical properties of the obtained state, we evaluate the linear entropy and atomic population inversion, numerically.
