Control of the electromagnetic waves in nano-scale structured materials is\ncentral to the development of next generation photonic circuits and devices. In\nthis context, hyperbolic metamaterials, where elliptical isofrequency surfaces\nare morphed into surfaces with exotic hyperbolic topologies when the structure\nparameters are tuned, have shown unprecedented control over light propagation\nand interaction. Here we show that such topological transitions can be even\nmore unusual when the hyperbolic metamaterial is endowed with nonreciprocity.\nJudicious design of metamaterials with reduced spatial symmetries, together\nwith the removal of time-reversal symmetry through magnetization, is shown to\nresult in nonreciprocal dispersion and one-way topological phase transitions in\nhyperbolic metamaterials.\n
