TLDR
The plasmon dispersion relation of a quantum wire is derived by solving Maxwell's equations for an anisotropic dielectric waveguide including retardation effects and the group velocity of the one-dimensional electron gas is found to be finite and given by the Fermi velocity.Abstract:
The plasmon dispersion relation of a quantum wire is derived by solving Maxwell's equations for an anisotropic dielectric waveguide including retardation effects. In the long-wavelength limit, and for the extreme quantum limit, the group velocity of the one-dimensional electron gas is found to be finite and given by the Fermi velocity.read more

Plasmons and magnetoplasmons in semiconductor heterostructures
TL;DR: In this article, the status of the theory and experiment which can contribute to our knowledge of plasmon excitations in synthetic semiconductor heterostructures is surveyed. But, beyond the presentation of the results achieved, there is a need to examine carefully the methodologies employed to obtain such results.

Nonlocal effects in the plasmons of nanowires and nanocavities excited by fast electron beams
Javier Aizpurua,A. Rivacoba +1 more
TL;DR: In this paper, the solutions of surface modes in cylindrical metallic wires and cavities are obtained within a nonlocal dielectric formalism, and energy-loss spectra due to surface-plasmon excitation are calculated with use of the nonlocal formalism both for electron trajectories near a metallic nanowire and a metallic nocavity.
Journal ArticleDOI
Time-dependent transport through molecular junctions
TL;DR: This work investigates transport properties of molecular junctions under two types of bias--a short time pulse or an ac bias--by combining a solution for Green's functions in the time domain with electronic structure information coming from ab initio density functional calculations.

Collective effects in condensed conducting phases including low-dimensional systems
Norman H. March,M. P. Tosi +1 more
TL;DR: In this paper, the authors considered plasmons, phonons plus electron-phonon collective effects, phase changes especially in relation to metal-non-metal transitions, and Luttinger liquids.

Theory of confined plasmonic waves in coaxial cylindrical cables fabricated of metamaterials
TL;DR: In this paper, the dispersion properties of the plasmonic wave excitations in such multi-interface structures are characterized by the electromagnetic fields that are localized at and decay exponentially away from the interfaces.
