| Sumario: | We study the interaction between the single-mode electromagnetic field and the pair of
indistinguishable two-level atoms via the intensity-dependent coupling. This problem is
equivalent to the equidistant three-level atom with equal dipole moment matrix transition
elements between the adjacent levels. The exact analytical solution for the tom-field state-
vector is obtained assuming that at the initial moment the field is in the Holstein-Primakoff
SU (1,1) coherent state. The quantum-statistical and squeezing properties of the field are investigated. The obtained results are compared with those for the single two-level atom. It is
observed that the exact periodicity of the field squeezing that takes place in the case of the
single two-level atom is violated in the case of the pair of cold atoms. In other words, the exact periodicity of the physical quantities can be destroyed only if the radiation field interacts with a system of more than one two-level atom. |
