ОБРАЗОВАНИЕ КВАНТОВЫХ ВИХРЕЙ ПРИ ИОНИЗАЦИИ АТОМА СВЕРХКОРОТКИМ ЛАЗЕРНЫМ ИМПУЛЬСОМ: 2D- И 3D-СЛУЧАИ

What is it about?

Quantum vortices formed at the barrier-suppression ionization of an atom by an ultrashort laser pulse have been studied theoretically and numerically. The ionization of a hydrogen atom is considered in the two-dimensional space and the ionization of an atom in the zero-range potential approximation is considered in the three-dimensional space. The resulting analytical expressions imply that the localization of quantum vortices in the three-dimensional space can be predicted by analyzing the two-dimensional model.
