We describe a method to create effective gauge potentials for stationary-light polaritons. When stationary light is created in the interaction with a rotating ensemble of coherently driven double-Lambda type atoms, the equation of motion is that of a massive Schrödinger particle in a magnetic field. Since the effective interaction area for the polaritons can be made large, degenerate Landau levels can be created with degeneracy well above 100. This opens up the possibility to study the bosonic analogue of the fractional quantum Hall effect for interacting stationary-light polaritons.
我们描述了一种为定域光极化激元创建有效规范势的方法。当定域光在与相干驱动的双 Λ 型原子旋转系综相互作用时产生，运动方程就是处在磁场中的质量为 Schrödinger 粒子的方程。由于极化激元的有效相互作用面积可以做得很大，因此可以产生简并度超过 100 的简并朗道能级。这为研究相互作用的定域光极化激元的玻色分数量子霍尔效应提供了可能性。
