摘要

Theoretical results for single-electron states of lens-shaped self-assembled quantum dots under intense harmonic electric fields are presented. We analyze the time evolution of the system utilizing a nonperturbation Floquet state approach. The full lens geometry is taken into account, allowing us to study the interplay between the spatial asymmetry of the confinement and the magnitude, direction, and frequency of the applied field. Dynamical symmetries and localization are revealed in the structure of Hilbert space of functions and the associated quasienergy spectrum. We discuss the role of the different quasienergy sidebands as the parameters of the system change for light incident parallel and perpendicular to the lens axis. We find that the contribution of different drive harmonics is controlled by fine tuning of field intensity. We further show that avoided crossings in the quasienergy spectrum are correlated with the spectral force of the sidebands and dynamical state localization.
