Based on the recently proposed concept of effective gauge potential and magnetic field for photons, we numerically demonstrate a photonic de Haas-van Alphen effect. We show that in a dynamically modulated photonic resonator lattice exhibiting an effect magnetic field, the trajectories of the light beam at a given frequency have the same shape as the constant energy contour for the photonic band structure of the lattice in the absence of the effective magnetic field.
基于最近提出的光子有效规范势和磁场的概念，我们通过数值方法证明了光子德哈斯 - 范阿尔芬效应。我们表明，在呈现有效磁场的动态调制光子谐振器晶格中，给定频率下光束的轨迹与不存在有效磁场时晶格光子能带结构的恒定能量轮廓具有相同的形状。
