摘要:

通过控制场随时间的变化,光的相干态和单光子态都被存储在冷原子气体中,并从冷原子气体中恢复出来。研究了在外加磁场中,提取效率与存储时间的关系。一系列的崩溃和复苏的观察,在非常好的协议与理论预测。观测结果用原子自旋波和光波的集体激发(称为暗态极化激元)的时间演化来解释。

英文摘要:

By time-dependent variation of a control field, both coherent and single photon states of light are stored in, and retrieved from, a cold atomic gas. The efficiency of retrieval is studied as a function of the storage time in an applied magnetic field. A series of collapses and revivals is observed, in very good agreement with theoretical predictions. The observations are interpreted in terms of the time evolution of the collective excitation of atomic spin wave and light wave, known as the dark-state polariton.
