Analyzed the non-equilibrium response of the electron system to weak measurement fields.

Provided insights into impurity-induced transitions between Landau-Floquet states.

Abstract

Kinetics of spatially uniform distribution of 2D electrons in crossed electric and magnetic fields in the presence of microwave radiation has been studied. In the present model the contribution from the microwave radiation and the effects of Landau quantization are considered exactly, while scattering is treated perturbatively. Here Landau--Floquet states interact with the impurity potential that causes transitions between them. The linear response of a non-equilibrium system to a weak measurement field has been considered for the case when the non-equilibrium state of the carriers can be described by the average values of the total energy and the number of particles.
