Abstract
We predict a double-resonant feature in the magnetic field dependence of the phonon-mediated mobility of a two-subband quasi-two-dimensional electron system. These resonances take place when two Landau levels corresponding to different size-quantized subbands are close to each other but do not coincide. We also discuss the effect of non-equilibrium phonons. Rabi-like oscillations of electron population and emission of the phonons at new frequencies are predicted.
