Semiclassical theory of vibrational energy relaxation

Robert Karrlein, Hermann Grabert

摘要:

本文提出了一种基于量子主方程半经典处理的振动能弛豫理论。利用偶极矩阵元的半经典展开的新结果,我们表明,在经典极限的主方程减少到Zwanzig能量扩散方程。确定并讨论了谐波势和莫尔斯势的主要量子修正。

英文摘要:

A theory of vibrational energy relaxation based on a semiclassical treatment of the quantum master equation is presented. Using new results on the semiclassical expansion of dipole matrix elements, we show that in the classical limit the master equation reduces to the Zwanzig energy diffusion equation. The leading quantum corrections are determined and discussed for the harmonic and Morse potentials.
