Two-flux tunable Aharonov-Bohm caging in a photonic lattice
arXiv:2102.06682 · doi:10.1103/PhysRevB.104.024306
Abstract
We study the Aharonov-Bohm caging effect in a one-dimensional lattice of theta-shaped units defining a chain of interconnected plaquettes, each one threaded by two synthetic flux lines. In the proposed system, light trapping results from the destructive interference of waves propagating along three arms, this implies that the caging effect is tunable and it can be controlled by changing the tunnel couplings . These features reflect on the diffraction pattern allowing to establish a clear connection between the lattice topology and the resulting AB interference.
