Two-dimensional localization effect via spatialdependent quantum interference in an asymmetric double quantum dot nanostructure

摘要

We investigate the two-dimensional (2D) population distribution in a semiconductor quantum dot nanostructure driven by two orthogonal standing-wave lasers. It is found that, due to the position-dependent quantum interference effect, the 2D spatial population distribution of two upper states can be easily controlled via adjusting the system parameters. Thus, our scheme shows the underlying probability for the formation of the 2D localization effect in a solid.
