摘要
为研究四能级单分子磁体中的电磁诱导透明现象,利用薛定谔方程,求解出概率幅运动方程,运用了微扰理论给出了单分子磁体系统对弱场响应的解析表达式,通过选取适当的参数,给出了概率幅方程的数值模拟结果,结果表明,当探测光与耦合光共振时,单分子磁体系统中会出现一个透明窗口,即电磁诱导透明现象。并分析了控制场强度和强场失谐量对透明窗口的影响。
This paper studies the phenomenon of Electromagnetically Induced Transparency(EIT)in a four-level single-molecule magnet.By using the schrodinger equation,we obtain the magnetic molecule equations of motion.The perturbation theory is used to give the analytical formula for the response of the single-molecule magnet system to the probe light field.By selecting appropriate parameters,the numerical simulation results of the motion equation are given.The results show that when the probe light and the coupled light resonate,a transparent window appears in the single-molecule magnet system,that is the electromagnetically induced transparency phenomenon.
