Abstract :
We explore the pattern of effective mass dependence of linear and non-linear optical (NLO) response of one electron quantum dots harmonically confined in two dimensions. For different combinations of transverse magnetic field strength (ωcωc), harmonic confinement potential (ω0ω0), and anharmonic interaction, the influence of the effective mass (m*m*) of the dot on linear (αα), and the first (ββ), and second (γγ) NLO responses of the system is computed through linear variational route. The investigation reveals a complicated interplay between the effective mass and the system parameters.
