耗散诱导的Tonks-Girardeau光子气体

Dissipation induced Tonks-Girardeau gas of photons

Martin Kiffner, Michael J. Hartmann

摘要:

本文描述了一种产生具有纯耗散相互作用的Tonks-Girardeau光子气体的方案。我们提出了一个主方程方法来描述原子四能级介质中的定态光,并表明,在适当的条件下,两个粒子衰变是主要的光子损失机制。与色散双光子过程相比,这些耗散双光子损失使相互作用强度增加至少一个数量级,并且可以将光子驱动到Tonks-Girardeau制度中。不同的情况下观测的光子之间的费米子相关性的Tonks-Girardeau气体制度进行了讨论。

英文摘要:

A scheme for the generation of a Tonks-Girardeau gas of photons with purely dissipative interaction is described. We put forward a master equation approach for the description of stationary light in atomic four-level media and show that, under suitable conditions, two particle decays are the dominant photon loss mechanism. These dissipative two-photon losses increase the interaction strength by at least one order of magnitude as compared to dispersive two-photon processes and can drive the photons into the Tonks-Girardeau regime. Different scenarios for the observation of fermionic correlations between photons in the Tonks-Girardeau gas regime are discussed.
