We scrutinize the behavior of eigenvalues of an electron in a helium (He) atom as it interacts with electric field directed along the z-axis and is exposed to linearly polarized intense laser field radiation. To achieve this, we freeze one electron of the He atom at its ionic ground state and the motion of the second electron in the ion core is treated via a more general case of screened Coulomb potential model. Using the Kramers–Henneberger (KH) unitary transformation, which is the…

Dichotomy of the exciton wave function in semiconductors under intense laser fields

We study the behavior of excitons in a semiconductor irradiated by a monochromatic, linearly polarized, intense laser field. By taking the finiteness of the hole effective mass into account and

Numerical simulation of the double-to-single ionization ratio for the helium atom in strong laser fields

We present calculations on the ratio between double and single ionization of helium by a strong laser pulse at a wavelength of 780 nm using the quantitative rescattering (QRS) model. According to

Electron-impact elastic scattering of helium in the presence of a laser field: non perturbative approach

We report a detailed analysis of electron-helium scattering in the presence of a laser field; focusing on the elastic process of helium atoms from the ground state 11S. The process under

Atoms in strong laser fields

Theory The theoretical problem consists in solving the time-dependent Schrodinger equation (TDSE) that describes the interaction of a ~any-electron atom with a laser field. During many years,

The time-dependent Schroedinger equation for the helium atom with a model potential is solved on a numerical grid and it is found that the harmonics with order higher than 13 are due to the ion when the photon energy is 5.0 eV.

Harmonic generation beyond the saturation intensity in helium.

The approach is based on a two-step procedure where the neutral atom response in the single active electron approximation is calculated and it is observed that harmonics are still produced by the neutral atoms above the saturation intensity, but the simple classical law for the cutoff is not obeyed.

Hydrogen atom in a quantum plasma environment under the influence of Aharonov-Bohm flux and electric and magnetic fields.

It is found that to perpetuate a low-energy medium for the hydrogen atom in quantum plasmas, a strong electric field and weak magnetic field are required, whereas the AB flux field can be used as a regulator.
