Electron-electron interaction effects in quasi-one-dimensional conducting polymers and related systems

Coherent electron transport in quasi one-dimensional carbon-based systems

This Colloquium discusses the coherent electron transport properties of non-ideal quasi-onedimensional carbon-based systems, i.e. graphene nanoribbons, carbon nanotubes and linear chains. Results are based on numerical simulations that implement Schröedinger/Poisson as well as non-equilibrium polaronic methodologies for the calculation of quantities relative to the conduction. Attention is paid...

Calculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method

In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...

Dielectric response of a quasi-one-dimensional electron system

The dielectric response of a quasi-one-dimensional electron system is studied by including fluctuation effects (in the polarizability) and by using a recently derived analytic form for the electron-electron interactions. General forms for the polarizability matrices both for the intraand inter-subband cases are presented. The generalized polarizability is analytic over the whole region of the w...

Competition between triplet superconductivity and antiferromagnetism in quasi-one-dimensional electron systems

We investigate the competition between antiferromagnetism and triplet superconductivity in quasi-onedimensional electron systems. We show that the two order parameters can be unified using a SO(4) symmetry and demonstrate the existence of such symmetry in one-dimensional Luttinger liquids of interacting electrons. We argue that approximate SO(4) symmetry remains valid even when interchain hoppi...
