Description
This talk will survey recent theoretical and experimental works on intrinsic nonreciprocity of quantum materials, as manifested by direction-dependent electrical resistivity. I will highlight two types of colossal nonreciprocal transport phenomena: (1). nonlinear Hall effect leading to divergent nonreciprocity in transverse resistance; (2) superconducting diode effect leading to 100% nonreciprocity in longitudinal resistance. Applications of nonreciprocal quantum materials in terahertz electronics, energy harvesting and cryogenic computing will be discussed.
