Abstract / Description:The charge-density magnetoexcitations in the bilayer electron
system have been studied by means of inelastic light-scattering
spectroscopy. Two principal magnetoplasma excitations of
different symmetry, acoustical and optical magnetoplasmons,
were observed. These principal excitations couple with in-phase
and out-of-phase Bernstein modes at nonzero in-plane momentum
through the many-body Coulomb interaction. Detailed
measurements of the coupled mode energies were performed and
compared with theoretical calculations.
