三能级原子与光场的动力学演化特性
Entanglement Dynamics of Three-Level Atoms with Light Fields
摘要
Abstract
The system of three-level atom interacting with light field is studied by using the method of full quantum theory.Based on wave function,the dynamic evolution characteristics of different quantum states with the same coupling intensity are studied.In addition,the influence of different coupling intensi-ty of the same quantum state on the dynamic evolution characteristics of the system is discussed.The re-sults show that under the same coupling intensity,the population values of atoms in |b1＞states first de-crease and then increase with time,the population values of atoms in b2＞states and |b3＞states first in-crease and then decrease with time,and the corresponding population values of |b2＞states produce three peaks in the same period.The population values corresponding to the | b3＞states produce two peaks in the same period,and there is also a trough after the first peak,and the population values of different quantum states show periodic oscillations with time.In the same quantum state,with the increase of the coupling coefficient,the dynamic evolution oscillation characteristics of the quantum state between the light field and atoms are enhanced,and the system dynamic evolution pattern always maintains periodic changes with the increase of time.关键词
