Hybrid-impurity resonance in a quantum wire placed in a magnetic field

An analytical expression for the absorption coefficient of electromagnetic radiation in a quantum wire is obtained. We consider the case of a field lying in the plane perpendicular to the wire axis. The calculation is performed using second-order perturbation theory with consideration of electron scattering by ionized impurities. We demonstrate the resonant character of the absorption and find the position of resonance frequencies in the dependence on the magnitude and direction of the magnetic field.
