Quantum frequency doubling in the topological insulator Bi(2)Se(3)
The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling, which was recently observed in time-reversal-invariant materials. Here we report novel electric frequency doubling in the absence of BCD on a surface of the topological insulator Bi(2)Se(3) under zero magnetic...
