Query: Inelastic Coulomb scattering rate of a multisubband Q1D electron gas   In this work, the Coulomb scattering lifetimes of electrons in two coupled
quantum wires have been studied by calculating the quasiparticle self-energy
within a multisubband model of quasi-one-dimensional (Q1D) electron system. We
consider two strongly coupled quantum wires with two occupied subbands. The
intrasubband and intersubband inelastic scattering rates are caculated for
electrons in different subbands. Contributions of the intrasubband,
intersubband plasmon excitations, as well as the quasiparticle excitations are
investigated. Our results shows that the plasmon exictations of the first
subband are the most important scattering mechanism for electrons in both
subbands.
