Diatomic dications and dianions are attractive species for quantum chemists and
spectroscopists. In comparison with neutral diatomics, these species show a wealth of …

The time-dependent wave function of a nanoring driven by a laser field is obtained by
exploiting the symmetries inherent to the system and used for studying the properties of the …

We report a new version of fermion coupled coherent states method (FCCS-II) to simulate
two-electron systems based on a self-symmetrized six-dimensional (6D) coherent states …

Contributions of the pre-ionized H 2 (PI-H 2) and ionized ${{\rm {H}}} _ {2}^{+} $ subsystems
of the two-electron H 2 system to its high-order harmonic generation in eight-cycle sin 2-like …

In our previous report, we introduced a new version of Fermion coupled coherent states
method (FCCS) which was especially suited for simulating the first symmetric spatial …

We point out the dependence of ionization probability and the high-order harmonics
intensity on vibration levels of H 2+. The ionization probability shows a maximum value at a …

Abstract Effects of the laser pulse wavelength and intensity on the high harmonic generation
(HHG) production from the ionic and homolytic pre-ionization transient states of the two …

One of the valuable achievements in nonlinear nonpertubative optics is the production of
attosecond laser pulses by using high-order harmonic generation (HOHG) measured in …
