Strong-field double ionization dynamics of vibrating HeH versus HeT
S. Wang, R. H. Xu, W. Y. Li +4
We study double ionization (DI) dynamics of vibrating HeH versus its isotopic variant HeT in strong laser fields numerically. Our simulations show that for both cases, thes…
Alpha decay in intense laser fields: Calculations using realistic nuclear potentials
Jintao Qi, Tao Li, Ruihua Xu +2
We calculate the effect of intense laser fields on nuclear alpha decay processes, using realistic and quantitative nuclear potentials. We show that alpha decay rates can indeed be…
On the longitudinal momentum of the electron at the tunneling exit
Ruihua Xu, Tao Li, Xu Wang
The longitudinal momentum of the electron at the tunneling exit is a useful quantity to make sense of the tunneling ionization process. It was usually assumed to be zero from a cla…
Time-domain theory of atomic photoionization
Ruihua Xu, Zhaoyan Zhou, Xu Wang
We present a combined numerical and theoretical study of atomic photoionization in the time domain. We show how a photoelectron wave packet rapidly changes its shape after being em…
