Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Giacomo Sala, Giacomo Sala, , , | Summary: The surface states of 3D topological insulators possess geometric structures that imprint distinctive signatures on electronic transport. A prime example is the Berry curvature, which controls electric frequency doubling via a higher order moment, called Berry curvature triple. […]
