Generation of adiabatic pulses

Abstract

A two-dimensional GaAs/AlGaAs quantum disk under the influence of a non-central potential resulting in azimuthal distortion, subjected to an external static electric field, is exposed to a linearly polarized laser pulse. Adiabatic magnetic pulses are found to be generated due to the introduction of distortion in the system. The magnitude of distortion is expected to serve as one of the crucial control parameters for the manipulation of the generated magnetic pulses. The production of desired magnetic pulses may prove beneficial in many bio-medical applications. • A distorted GaAs/AlGaAs quantum disk is exposed to sub-picosecond laser pulse. • Non-zero radial charge currents in addition to the azimuthal components are observed. • Optimized laser parameters are found to generate pure adiabatic magnetic pulses. • These photo-induced pulses are much prominent in case of finite azimuthal distortion. • Such magnetic pulses may prove beneficial for various bio-medical applications.
