For a molecule irradiated by an intense laser field, the sudden excitation or removal of an electron will trigger ultrafast electronic and nuclear dynamics, of which the timescales are usually several orders different and can be separately treated according to the Born–Oppenheimer approximation. However, the electrons and nuclei are intrinsically coupled in a molecule and should be considered on an equal footing in strong laser fields. In this paper, we review the recent progresses made on the correlated electron–nuclear dynamics of molecules exposed to strong laser fields, in particular, the multiphoton energy absorption and deposition in molecular dissociative ionization. Moreover, the electron–nuclear correlation offers an alternative visual angle to capture the fascinating strong-field molecular dynamics, including the photon-number-resolved asymmetric dissociative single ionization, high-order above-threshold dissociation, and Rydberg states excitation in dissociative frust...

强激光场中分子的相关电子核动力学

对于由强激光场照射的分子,电子的突然激发或去除将触发超快的电子和核动力学,其时标通常相差几个数量级,可以根据Born–Oppenheimer近似法进行单独处理。但是,电子和原子核本质上是耦合在一个分子中的,因此应在强激光场中平等地考虑它们。在本文中,我们回顾了暴露于强激光场的分子在相关的电子核动力学方面的最新进展,特别是分子解离电离中的多光子能量吸收和沉积。此外,电子-核相关性提供了另一种视角来捕获引人入胜的强场分子动力学,
