    Theory of the Pseudospin resonance in semiconductor bilayers
    (The American Physical Society, 2007) Abedinpour, S. H.; Polini, M.; MacDonald, A. H.; Tanatar, Bilal; Tosi, M. P.; Vignale, G.
    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 many-body theory of the dependence of the energy and the damping of this mode on layer separation d. Based on these results, we discuss the possibilities of realizing transport-current driven pseudospin-transfer oscillators in semiconductors, and of using the pseudospin-transfer effect as an experimental probe of intersubband plasmons.
