Effect of Berry phase on nonlinear response of two-dimensional fermions
We develop a theory of nonlinear response to an electric field of two-dimensional (2D) fermions with topologically nontrivial wave functions characterized by the Berry phase Φ_{n}=nπ,n=1,2,.... In particular, we find that owing to the suppression of backscattering at odd n, Hall field-induced resist...
