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

Highlights: • A spherically confined atom in a Hulthen plus a ring-shaped potential is studied. • The persistent current and induced magnetic field for this system are evaluated. • Interaction of the above atomic system with laser pulse is explored. • Various pulse parameters significantly influence the transition probabilities. • The effect of pulse parameters is much more profound than that of magnetic field. -- Abstract: In this work we propose to study an atom confined in a potential which consists of a Hulthén potential plus a ring-shaped potential. The atom is further subjected to a spherical confinement. The time-independent Schrödinger 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.
