凝聚相环境中的相干核运动：波包方法和泵浦探测光谱学
Coherent nuclear motion in a condensed-phase environment: Wave-packet approach and pump-probe spectroscopy
摘要：
本文发展了一种理论描述凝聚相环境中核运动的量子力学高斯波包方法。给出了谐振子势面的含时约化密度矩阵的一般表达式，并给出了微观系统加浴模型的精确量子动力学。特别注意的是，系统和浴泵探测实验的结果之间的初始相关性的影响。我们表明，标准的因子分解制备，相比一个更现实的相关准备，导致显着不同的受激发射光谱在高温下。最近的实验反应中心进行了分析，使用这种形式主义。
英文摘要：
A quantum-mechanical Gaussian wave-packet approach to the theoretical description of nuclear motions in a condensed-phase environment is developed. General expressions for the time-dependent reduced density matrix are given for a harmonic potential surface, and the exact quantum dynamics is found for a microscopic system-plus-bath model. Particular attention is devoted to the influence of initial correlations between system and bath for the outcome of a pump-probe experiment. We show that the standard factorized preparation, compared to a more realistic correlated preparation, leads to significantly different stimulated emission spectra at high temperatures. Recent experiments for the reaction center are analyzed using this formalism.
