Common myth suggests synchronicity and unidirectionality of nuclear and electronic fluxes. Accurate quantum dynamics simulations of the vibrating model system, aligned H2+, confirm this rule, but with exceptional opposite behaviours during short peri

The enhancement of photodesorption cross sections by shaped laser pulses is demonstrated here using quantum dynamical methods. Two model systems are chosen. The first one is H:Si(1 0 0)-(2 × 1), where IR laser-induced desorption of H atoms by “lad

Koopmans’ picture predicts that the ith ionisation potential IP i is approximately equal to the negative orbital energy −e i of the molecular orbital ϕ i occupied by the single active electron (SAE), which is ionised, IP i = −e i . The corresp

The dynamics of vibrational excitation of ppe, pde, ddμ and dtμ in very intense laser fields (I0 ∼ 1014 W/cm2 for ppe and pde, and I0 ∼ 1020 and 1022 W/cm2 for ddμ and dtμ) is studied by the numerical solution of the time-dependent Schrodinge

The time-dependent self-consistent field (TDSCF) approach is developed and applied to study the free relaxation and the infrared-laser-driven desorption of H atoms from a H:Si(100)-(2 × 1) surface. The method has made it possible to treat, by means

The dynamics of multiphoton excitation of HD+ and H 2 + in quasi-resonant infrared intense laser fields (I0 = 1.18 × 1014 W/cm2) is studied by the numerical solution of the time-dependent Schrodinger equations for the systems with explicit treatment
