光子和极化激元的量子相变

Quantum phase transitions with Photons and Polaritons

Fernando G. S. L. Brandao, Michael J. Hartmann, Martin B. Plenio

摘要:

我们表明,一个系统的极化激元-结合原子和光子的激发-在一个阵列的耦合腔,根据通常认为在电磁感应透明的实验装置,描述的玻色-哈伯德模型。这开辟了使用该系统作为量子模拟器的可能性,允许观察量子相变和测量局部属性,如单点可观测值。所提出的设置的所有基本构件已经通过实验实现,表明其在不久的将来实现的可行性。

英文摘要:

We show that a system of polaritons - combined atom and photon excitations - in an array of coupled cavities, under an experimental set-up usually considered in electromagnetically induced transparency, is described by the Bose-Hubbard model. This opens up the possibility of using this system as a quantum simulator, allowing for the observation of quantum phase transitions and for the measurement of local properties, such as single site observables. All the basic building blocks of the proposed setting have already been achieved experimentally, showing the feasibility of its realization in the near future.
