Abstract
The pseudospin degree of freedom in a semiconductor bilayer gives rise to a collective mode analogous to the ferromagnetic resonance mode of a ferromagnet. We present a theory of the dependence of the energy and the damping of this mode on layer separation . Based on these results, we discuss the possibility of realizing transport-current driven pseudospin-transfer oscillators in semiconductors.
