Photonic Bloch oscillations of correlated particles
摘要:
基于光在含有缺陷线的方形波导阵列中的空间输运,提出了一维周期晶格上两个关联电子的布洛赫振荡(BO)的光子学实现方法.相关BO的签名,例如由粒子相互作用引起的振荡频率的倍频,可以通过监测激发缺陷线附近的阵列的光束所遵循的空间路径来简单地可视化。
英文摘要:
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.
