By solving the full-dimensional time-dependent Schrödinger equation with the thermal-random-phase wavepacket method, we investigate the photoassociation (PA) process of hot (1000 K) magnesium atoms induced by two time-delayed femtosecond laser pulse

The atom-atom-anion three-body recombination (TBR) of ^{3}He+^{3}He+X^{−}(X=HorD) systems at ultracold temperatures (T=0.01∼100 mK) are studied by solving the Schrödinger equation in the adiabatic hyperspherical representation. It is found that

Chinese Journal of Chemical Physics. 35:295-302
We performed extensive quasiclassical trajectory calculations for the H+C2D2→HD+C2D/D2+C2H reaction based on a recently developed, global and accurate potential energy surface by the fundamental-invariant neural network method. The direct abstracti

The ultracold state-to-state chemistry for three-body recombination (TBR) in realistic systems has recently been experimentally investigated with full quantum state resolution. However, many detected phenomena remain challenging to be explored and ex

We report two novel roaming pathways for the H + C2H2 → H2 + C2H reaction by performing extensive quasiclassical trajectory calculations on a new, global, high-level machine learning-based potential energy surface. One corresponds to the acetylene-

Roaming is a novel mechanism in reaction dynamics. It describes an unusual pathway, which can be quite different from the conventional minimum-energy path, leading to products. While roaming has been reported or suggested in a number of unimolecular
