Quantum frequency doubling in the topological insulator Bi2Se3
Berry curvature dipole (BCD) leads to the nonlinear Hall effect manifested as a frequency doubling in topological materials. Here, the authors report electric frequency doubling in the absence of BCD and magnetic field on a surface of Bi2Se3 due to skew scattering arising from inherent chirality of...
