Experimental Observation of Aharonov-Bohm Cages in Photonic Lattices
Experimental Observation of Aharonov-Bohm Cages in Photonic Lattices
We report on the experimental realization of a uniform synthetic magnetic flux and the observation of Aharonov-Bohm cages in photonic lattices. Considering a rhombic array of optical waveguides, we engineer modulation-assisted tunneling processes that effectively produce nonzero magnetic flux per plaquette. This synthetic magnetic field for light can be tuned …
