Abstract
We have calculated the photoconductance of a parabolic quantum wire subject to a magnetic field. It is shown that the photoconductance has maxima in the vicinity of a threshold of ballistic conductance steps. Electromagnetic irradiation is found to decrease the resistance of the quantum wire. The dependence of the photoconductance on the radiation frequency, on the magnetic field, and on the electron energy is investigated.
