Název v původním jazyce

Linear entropy and squeezing of the interaction between two quantum system described by su (1,1) and su(2) Lie group in presence of two external terms

Popis výsledku v původním jazyce

A Hamiltonian, that describes the interaction between a two-level atom (su(2) algebra) and a system governed by su(1, 1) Lie algebra besides two external interaction, is considered. Two canonical transformations are used, which results into removing the external terms and changing the frequencies of the interacting systems. The solution of the equations of motion of the operators is obtained and used to discuss the atomic inversion, entanglement, squeezing and correlation functions of the present system. Initially the atom is considered to be in the excited state while the other systems is in the Perelomov coherent state. Effects of the variations in the coupling parameters to the external systems are considered. They are found to be sensitive to changing entanglement, variance and entropy squeezing.
