Over-Barrier Ionization Dynamics Studied by Backpropagation
Yongzhe Ma, Qingcao Liu, Hongcheng Ni +1
Tunneling and over-barrier ionization are the primary processes of strong-field ionization of atoms and molecules. While the dynamics of tunneling ionization have been extensively…

Instantaneous Quasiphoton in Strong-Field Ionization
Yongzhe Ma, Hongcheng Ni, Yang Li +2
Photon is a concept that does not apply at the instantaneous level when light is described by classical electromagnetic fields. Exploiting the dynamical rotational symmetry of circ…
