Abstract

In this paper, we investigate the total absorption coefficient, refractive index change coefficient, second harmonic generation and third harmonic generation of quantum dots in a weakly coupled quantum plasma under the effects of an Aharonov–Bohm flux field, topological defect and uniform magnetic field. The calculations are carried out via the Pekar variational method and compact density matrix approach. By solving the Schrodinger equation, the energy levels are derived. Then, using the obtained energy eigenvalues, we deduce the optical properties of the considered system. Our results show that with significant variations in the magnitudes of the parameters, either a redshift or a blueshift and maximum and minimum resonance appear.
