In the pantheon of topological materials, Weyl semimetals have been a persistent focus due to the predictions of interesting anomalous effects such as the chiral anomaly, the Nieh-Yan anomaly, and axion electrodynamics, that are normally expected to be found in the realm of high-energy physics rather than condensed matter physics. Nonetheless, while theoretically feasible, the observation of...
We propose Berry phase enforced spinor superconducting orders arising from pairing topological Fermi surfaces with their Chern numbers differing by an odd integer. This exotic pairing structure can exhibit a single pairing gap node on a Fermi surface and is described by monopole harmonics with half-integer charge and fractionalized half-integer partial-wave symmetry. We investigate...
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%...
