论文摘要
时间和角分辨光电光谱是一种测量固体中电子动力学的强大技术。该技术的最新进展促进了对激发声子对电子结构具有的效果的能量解析的观察。在这里，我们在\ textit {ab intio}模拟的帮助下，表明，具有激发的声子模式的固定测量值的傅立叶分析实际上是对面包和模式分辨的电子波的观察，直接从实验数据中观察到了band和模式的电子孔子，而无需理论计算。
Time and angular resolved photoelectron spectroscopy is a powerful technique to measure electron dynamics in solids. Recent advances in this technique have facilitated band and energy resolved observations of the effect that excited phonons, have on the electronic structure. Here, we show with the help of \textit{ab initio} simulations that the Fourier analysis of time-resolved measurements of solids with excited phonon modes leads, in fact, to an observation of the band- and mode-resolved electron-phonon coupling directly from the experimental data and without need for theoretical computations.
