Generation and nonclassicality of entangled states via the interaction of two three-level atoms with a quantized cavity field assisted by a driving external classical field

摘要: The interaction of two identical three-level atoms the types $$V,\,\varXi $$V,? and $$\varLambda $$? with a quantized cavity field as well driving external classical is studied. Under certain unitary transformations, system converted to typical form Jaynes---Cummings model for atoms. exact analytical solutions wave function different considered atom---field systems are exactly obtained help Laplace transform technique, when initially prepared in topmost excited state coherent state. In order examine nonclassicality features deduced states, dynamics entanglement between subsystems discussed via well-known measures, namely, von Neumann entropy reduced negativity. addition, we pay attention temporal behavior quantum statistics photons squeezing phenomenon. Meanwhile, influence on latter physical quantities analyzed detail. results show that mentioned can be sensitively controlled field. Also, numerical computations imply fact $$\varXi $$?-type atomic more visible than other configurations. it shown particular case system, rank density matrix no larger three, so negativity fully captures this such distillable.
