Persistent currents and induced magnetization in presence of external magnetic field and transition probabilities in presence of combined laser pulse and external magnetic field for a confined hydrogen atom

摘要

In this work we propose to study an atom confined in a potential which consists of a Hulthen potential plus a ring-shaped potential. The atom is further subjected to a spherical confinement. The time-independent Schrodinger equation (TISE) of the system is solved numerically. Exact energy levels are obtained. The persistent current and induced magnetic field of such a confined atom is evaluated. Finally, the atomic system in this potential and confinement is subjected to short electromagnetic pulses, which are shown to induce enormous currents. (C) 2019 Elsevier B.V. All rights reserved.
