Correlation Effects on the Coupled Plasmon Modes of a Double Quantum Well
arXiv:cond-mat/9703066 · doi:10.1103/PhysRevLett.78.2204
Abstract
At temperatures comparable to the Fermi temperature, we have measured a plasmon enhanced Coulomb drag in a GaAs/AlGaAs double quantum well electron system. This measurement provides a probe of the many-body corrections to the coupled plasmon modes, and we present a detailed comparison between experiment and theory testing the validity of local field theories. Using a perpendicular magnetic field to raise the magnetoplasmon energy we can induce a crossover to single-particle Coulomb scattering.
