Robust nonequilibrium surface currents in the three-dimensional Hofstadter model
Genuinely two-dimensional robust crosscurrents—which flow against the natural direction of heat flux— have been missing since the discovery of their one-dimensional counterpart. We provide a setup to realize them on a cubic three-dimensional (3D) lattice hosting a Hofstadter model coupled to two hea...
