报告摘要：
Tracing electron dynamics in real time is central to the understanding and exploring of the fundamental photophysical and photochemical processes. We demonstrated that the quantum time delays of different ionization pathways in strong-field dynamics can be clearly resolved and extracted with semiclassical statistical methods and a large number of elenctron trajectories. Our results unified the seemingly opposing quantum Eisenbud-Wigner-Smith time delay and classical Coulomb-induced time delay by highlighting the same physical picture. We employed deep learning to perform Feynman’s path integral approaches to demonstrate the classical-quantum correspondence. We found that some quantum mechanical concepts such as state, excitation and “resonance” in molecules can be expressed by statistical electron trajectories. We revealed the nonadiabatic tunneling dynamics in solid-state high harmonic generation.
