外文标题：Correlated tunneling in high-order above threshold dissociative ionization of H2

外文摘要：Comprehension of photon-triggered molecular processes is essential in the study of various important topics in physics,chem-istry,and biology.Here we propose a correlated tunneling picture to understand the dissociative ionization process of molecules in intense laser fields based on a quantum model developed in the framework of many-body S-matrix theory including nuclear vibrational motion.In this quantum correlation picture,the single ionization of H2 and the subsequent electron-ion recollision-induced dissociation are considered as an entangled correlated process.It enables us to attribute the interference pattern in the joint-energy spectra to combined effects of single-slit diffraction and multi-slit interference of correlated electron-nuclear wave packets in the time domain.Our work opens a new avenue to understanding molecular dissociative ionization processes in external fields.
