Physics-informed neural networks for solving saddle-point equations in strong-field physics with tailored fields
Jiakang Chen, Sufia Hashim, Carla Figueira de Morisson Faria
We develop an unsupervised physics-informed neural network to solve saddle-point equations (SPEs) governing direct above-threshold ionization (ATI) within the strong-field approxim…
Unravelling inter-channel quantum interference in below-threshold nonsequential double ionization with statistical measures
S. Hashim, C. Figueira de Morisson Faria
We present a systematic study of interchannel quantum interference in laser-induced nonsequential double ionization (NSDI) within the strong-field approximation. Focusing on the be…
Below threshold nonsequential double ionization with linearly polarized two-color fields II: Quantum interference
S. Hashim, D. HabiboviÄ, C. Figueira de Morisson Faria
We perform a systematic analysis of intra-channel quantum interference in laser-induced nonsequential double ionization with linearly polarized bichromatic fields, focusing on the…
Below threshold nonsequential double ionization with linearly polarized two-color fields I: symmetry and dominance
S. Hashim, D. HabiboviÄ, C. Figueira de Morisson Faria
We investigate laser-induced nonsequential double ionization with linearly polarized bichromatic fields, focusing on the recollision-excitation with subsequent ionization (RESI) me…
