从第一性原理看二阶非线性光学

Second-Order Nonlinear Optics from First Principles

Eleonora Luppi, Hannes Hübener, Valérie Véniard

摘要:

基于含时密度泛函理论,我们提出了一种新的第一性原理理论,用于计算宏观二阶极化率chi^(2)。我们的方法允许直接包括多体效应。我们应用该理论计算了立方半导体GaAs的二次谐波产生光谱,结果与实验符合得很好。

英文摘要:

We present a new first-principle theory for the calculation of the macroscopic second-order susceptibility chi^(2), based on the Time-Dependent Density-Functional Theory approach. Our method allows to include straightforwardly the many-body effects. We apply the theory to the computation of the Second-Harmonic Generation spectroscopy, showing a very good agreement with experiment for cubic semiconductor GaAs.
