Ionization and recombination times of high-order harmonic generation with single-photon ionization Open
We theoretically study high-order harmonic generation (HHG) involving an extreme ultraviolet (XUV) pulse and an intense infrared driving field, where the electron is ionized by absorbing a single XUV photon. Using a developed classical-tra…

Coulomb-induced emission time shifts in high-order harmonic generation from H2+ Open
Accurate emission times of high-order harmonic generation (HHG) are vital for high-precision ultrafast detection in attosecond science, but a quantitative analysis of Coulomb effects on this time is absent in the molecular HHG. Here, we in…

Cation field‐strength effects on ion irradiation‐induced mechanical property changes of borosilicate glass structures Open
We examine the impact of the glass network‐modifier cation field strength (CFS) on ion irradiation‐induced mechanical property changes in borosilicate (BS) glasses for the ternary M 2 O–B 2 O 3 –SiO 2 systems with M = {Na, K, Rb} and the q…

Revealing Coulomb time shifts in high-order harmonic generation by frequency-dependent streaking Open
When an atom is ionized by a strong laser pulse, the field can drive the released electron back to the parent ion and trigger the emission of a high-order harmonic photon with a frequency that is a function of the time of ionization. The a…

Probing dynamical symmetries by bicircular high-order harmonic spectroscopy beyond the Born-Oppenheimer approximation Open
We explore the possibility of bicircular high-order harmonic spectroscopy to probe the laser-induced dynamics of molecules in a non-Born-Oppenheimer treatment. The numerical solutions of the time-dependent Schrodinger equation for aligned …

Recollision dynamics analysis of high-order harmonic generation in solids Open
We theoretically investigate the dynamic processes of solid harmonics generation using the one-dimensional time-dependent density functional theory and the three-band recollision model. Compared with gas harmonics, more quantum paths contr…

Ellipticity dependence transition induced by dynamical Bloch oscillations Open
The dependence of high-harmonic generation (HHG) on laser ellipticity is investigated using a modified ZnO model. In the driving of a relatively weak field, we reproduce qualitatively the ellipticity dependence as observed in the HHG exper…

Progress of Selection Rules in High-Order Harmonic Generation Open
The high-order harmonic generation (HHG) has attracted much attention due to its wide application in attosecond science in last decades.The selection rules have also been broadly studied in experiments and theories since they play an impor…
