圆偏振光修饰半导体量子环中激子的Aharonov-Bohm效应

Aharonov-Bohm effect for excitons in a semiconductor quantum ring dressed by circularly polarized light

O. V. Kibis, H. Sigurdsson, I. A. Shelykh

摘要:

我们从理论上证明了在环状半导体纳米结构中,圆偏振光与激子的强耦合导致了环中激子顺时针和逆时针旋转的物理不等价性。因此,出现了与这些相反的旋转相对应的激子态的定态能量分裂。这种激子Aharonov-Bohm效应取决于圆偏振场的强度和频率,并且可以在最先进的光学实验中检测到。

英文摘要:

We show theoretically that the strong coupling of circularly polarized photons to an exciton in ring-like semiconductor nanostructures results in physical nonequivalence of clockwise and counterclockwise exciton rotations in the ring. As a consequence, the stationary energy splitting of exciton states corresponding to these mutually opposite rotations appears. This excitonic Aharonov-Bohm effect depends on the intensity and frequency of the circularly polarized field and can be detected in state-of-the-art optical experiments.
