Kerr介质中相干态光场与耦合Λ型三能级原子作用原子信息熵的性质
Information entropy properties of the atoms in the system of coupled Λ-type three-level atoms interacting with coherent field in Kerr medium
摘要
Abstract
The information entropy properties of the atoms of coupled A-type three-level atoms interacting with coherent field are studied by means of quantum theory, and discussed the time evolutions of the information entropy of the atoms via the average photon number,initial state of the atoms,detuning, coupling constant between the atoms and the coefficient of Kerr medium. Numerical calculation results show that the time evolutions of the information entropy properties of the atoms strongly dependent on the initial state of the system and the average photon number. Detuning,coupling constant between the atoms and the Kerr coefficient still make influence on the information entropy of the atoms.关键词
