A photonic realization of Bloch oscillations (BOs) of two correlated electrons that move on a one-dimensional periodic lattice, based on spatial light transport in a square waveguide array with a defect line, is theoretically proposed. The signature of correlated BOs, such as frequency doubling of the oscillation frequency induced by particle interaction, can be simply visualized by monitoring the spatial path followed by an optical beam that excites the array near the defect line.
基于具有缺陷线的方形波导阵列中的空间光传输，理论上提出了一种在一维周期格上运动的两个相关电子的布洛赫振荡（BOs）的光子实现。通过监测在缺陷线附近激发阵列的光束所经过的空间路径，可以简单地可视化相关 BO 的特征，例如粒子相互作用引起的振荡频率的两倍频。
