Abstract: | In low-dimensional systems with an asymmetric quantizing potential, an asymmetric electron energy spectrum ε(p)≠ε(−p), where p is the electron momentum, arises in the presence of a magnetic field. A consequence of such an energy spectrum is that momentum
transfer to the electron system in mutually opposite directions in the presence of an external perturbation is different.
Therefore, in the presence of a standing electromagnetic wave momentum is transferred from the wave to the electrons, which
gives rise to a new type of electromotive force.
