半导体量子点中的量子光学现象

Quantum optical phenomena in semiconductor quantum dots

J. Thomas Andrews

摘要:

在激子和双激子存在下,研究了人工原子(半导体量子点)中的量子光学现象。利用传统的含时微扰技术得到了解析结果。本文对CdS量子点在高Q腔中的实际样品作了数值估计。观察到激子和双激子态的量子拉比振荡、光子统计、粒子数反转的崩塌和恢复等量子光学现象。当双激子存在时,由于双激子与腔场的强耦合,使崩塌和回复现象变得更快。

英文摘要:

Quantum optical phenomena are explored in artificial atoms well known as semiconductor quantum dots, in the presence of excitons and biexcitons. The analytical results are obtained using the conventional time-dependent perturbation technique. Numerical estimations are made for arealistic sample of CdS quantum dots in a high-Q cavity. Quantum optical phenomena such as quantum Rabi oscillations, photon statistics and collapse and revival of population inversion in exciton and biexciton states are observed. In the presence of biexcitons the collapse and revival phenomenon becomes faster due to the strong coupling of biexciton with cavity field.
