The band geometric properties of quantum materials play an elemental role in the linear and nonlinear transport electrons. In this paper, we propose that interplay Berry curvature, orbital magnetic moment Lorentz force can induce a finite resistivity two dimensional systems presence perpendicular field. induced magnetoresistivity scales linearly with field is purely mechanical origin. This nove...

Charge carriers in magic angle graphene come eight flavors described by a combination of their spin, valley, and sublattice polarizations. When the inversion time reversal symmetries are broken substrate or strong interactions, degeneracy can be lifted corresponding bands filled sequentially. Due to non-trivial band topology Berry curvature, each is classified topological Chern number, leading ...

Abstract The Berry curvature provides a powerful tool to unify several branches of science through their geometrical aspect: topology, energy bands, spin and vector fields. While quantum defects–phase vortices skyrmions–have been in the spotlight, as rotational entities condensates, superfluids optics, dynamics multi-component fields remain little explored. Here we use two-component microcavity...
