具有阻尼的二能级系统的解析解
Analytical solutions for two-level systems with damping
摘要:
提出了一种将Bloch方程的任意解析解转化为Landau-Lifshitz-Gilbert方程的解析解的方法。这使得一个两级系统的动态阻尼的分析描述。该方法表明,阻尼使二能级系统的线性薛定谔方程变为非线性薛定谔方程。作为应用,结果表明阻尼对自诱导透明的影响相对较小,但破坏了动态局域化。
英文摘要:
A method is proposed to transform any analytic solution of the Bloch equation into an analytic solution of the Landau-Lifshitz-Gilbert equation. This allows for the analytical description of the dynamics of a two level system with damping. This method shows that damping turns the linear Schrödinger equation of a two-level system into a nonlinear Schrödinger equation. As applications, it is shown that damping has a relatively mild influence on self-induced transparency but destroys dynamical localization.
