We have investigated the elementary electronic excitations of the quasi-one-dimensional (1D) magnetoplasma in GaAs-AlGaAs quantum wires by resonant inelastic light scattering. In narrow quantum wire samples we observe the 1D intrasubband plasmon if a wave vector is transferred parallel to the wire direction. This 1D plasmon shows a negative dispersion with magnetic field, which arises from ...
