A semirelativistic formulation of light-matter interaction is derived using the so called
propagation gauge and the relativistic mass shift. We show that relativistic effects induced by …

We establish a numerical solution to the time-dependent Schrödinger equation employing
an adaptive, discontinuous spectral element basis that automatically adjusts to the …

The response of an atomic hydrogen system in the presence of an intense ultrashort laser
pulse is investigated by direct integration of the time-dependent Schrödinger equation. The …

The interaction of a hydrogen atom with a linearly (z-) polarized laser pulse is described by
numerical solution of the three-dimensional Schrödinger equation. Photo-ionization of the …

The time-dependent variational principle is used to optimize the linear and nonlinear
parameters of Gaussian basis functions to solve the time-dependent Schrödinger equation …

An investigation of the probability of hydrogen atom ionization by ultra‐short electromagnetic
pulses is carried out in the frame of perturbation theory We consider the case when the …

Above-threshold ionization of atoms by XUV short laser pulses is investigated close to the
resonant 1s–2p transitions. Both ab initio TDSE and a theoretical Coulomb–Volkov like …

We investigated the effect of higher order dispersion on ultrafast photoionisation with
Classical Trajectory Monte Carlo (CTMC) method for hydrogen and krypton atoms. In our …

The ionization of the water molecule by intense ultrashort half-cycle electric pulses is studied
theoretically. The formation of the electron wave packets in the continuum was investigated …

The probability of excitation and ionization of the hydrogen atom by short strong laser pulses
is calculated by solving numerically the time-dependent Schrödinger equation. The …
