Query: Nonlinear response of the quantum Hall system to a strong
  electromagnetic radiation   We study nonlinear response of a quantum Hall system in
semiconductor-heterostructures via third harmonic generation process and
nonlinear Faraday effect. We demonstrate that Faraday rotation angle and third
harmonic radiation intensity have a characteristic Hall plateaus feature. These
nonlinear effects remain robust against the significant broadening of Landau
levels. We predict realization of an experiment through the observation of the
third harmonic signal and Faraday rotation angle, which are within the
experimental feasibility.
