The authors propose and simulate photonic realizations of the Creutz and Creutz-Hubbard ladders, predicting Aharonov-Bohm caging, doublon caging at half flux, edge states, and a synthetic-dimension implementation scheme.
Four modes in a square lattice would suffice to implement our system

Topology and interactions in the photonic Creutz and Creutz-Hubbard ladders
The authors propose and simulate photonic realizations of the Creutz and Creutz-Hubbard ladders, predicting Aharonov-Bohm caging, doublon caging at half flux, edge states, and a synthetic-dimension implementation scheme.
