Phys. Rev. B 65, 245326 (2002) [5 pages]Collective and single-particle excitations in coupled quantum wires in magnetic fieldsReceived 13 March 2002; published 24 June 2002 The full spectra of magnetoplasmons and single-particle excitations are obtained of coupled one-dimensional electron gases in parallel semiconductor quantum wires with tunneling. We show the effects of the interwire Coulomb interaction and the tunneling, as well as the magnetic-field-induced localization on the elementary excitations in symmetric and asymmetric coulped quantum wire structures. The interacton and resonance between the plasmon and the intersubband single-particle excitations are found in magnetic fields. © 2002 The American Physical Society URL:
