电磁感应透明中的暗态极化激元

Dark-State Polaritons in Electromagnetically Induced Transparency

M. Fleischhauer, M. D. Lukin

摘要:

我们确定形式稳定的耦合激发光和物质(“暗态极化激元”)与电磁感应透明中的量子场的传播。暗态极化激元的性质如群速度由光和物质成分之间的混合角决定,并且可以在脉冲传播时由外部相干场控制。特别是,光脉冲可以被减速和“捕获”,在这种情况下,它们的形状和量子态被映射到物质的亚稳态集体态上。这种可逆的相干控制技术的可能应用进行了讨论。

英文摘要:

We identify form-stable coupled excitations of light and matter (``dark-state polaritons'') associated with the propagation of quantum fields in Electromagnetically Induced Transparency. The properties of the dark-state polaritons such as the group velocity are determined by the mixing angle between light and matter components and can be controlled by an external coherent field as the pulse propagates. In particular, light pulses can be decelerated and ``trapped'' in which case their shape and quantum state are mapped onto metastable collective states of matter. Possible applications of this reversible coherent-control technique are discussed.
