Nonlinear Ohmic electromagnetic response
Anwei Zhang, Zheng Cai, C. M. Wang
We systematically investigate nonlinear Ohmic responses in second-harmonic generation and bilinear magnetoelectric effects within the Matsubara Green's function formalism. The opti…

Magneto-nonlinear Hall effect in time-reversal breaking system
Anwei Zhang, Jun-Won Rhim
Magneto-nonlinear Hall effect is known to be intrinsic and requires time-reversal symmetry. Here we show that a new type of magneto-nonlinear Hall effect can occur in the time-reve…
