The authors study transport of interacting bosons through an Aharonov-Bohm cage - a building block of flat-band networks - with coherent pump and sink leads. By simultaneously employing mean-field, pseudoclassical, and genuine quantum approaches they identify different transport regimes through the cage, ranging from fully insulating to fully conducting regimes.
