Realistic Electron-Electron Interaction in a Quantum Wire
نویسندگان
چکیده
The form of an effective electron-electron interaction in a quantum wire with a large static dielectric constant is determined and the resulting properties of the electron liquid in such a one-dimensional system are described. The exchange and correlation energies are evaluated and a possibility of a paramagnetic-ferromagnetic phase transition in the ground state of such a system is discussed. Low-energy excitations are briefly described. Pacs: 71.10.-w, 71.10.Pm, 73.23.-b Typeset using REVTEX

Effect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

متن کاملBias-Induced Optical Absorption of Current Carrying Two-Orbital Quantum Dot with Strong Electron-Phonon Interaction (Polaron Regime)
The one photon absorption (OPA) cross section of a current carrying two-orbital quantum dot (QD) with strong electron-phonon interaction (polaron regime) is considered. Using the self-consistent non-equilibrium Hartree-Fock (HF) approximation, we determine the dependence of OPA cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...
متن کاملConductance increase by electron-phonon interaction in quantum wires.
We investigate the influence of electron-phonon interactions on the DCconductance Γ of a quantum wire in the limit of one occupied subband. At zero temperature, a Tomonaga-Luttinger-like renormalization of Γ to a value slightly larger than 2e2/h is calculated for a realistic quantum wire model.

متن کاملTunneling through a short interacting wire
We investigate tunneling through a short wire with electron-electron interactions which is coupled to noninteracting leads. We identify two temperature regimes (a) TKondo < T ≤ Twire = h̄vF /kBd (d is the length of the interacting wire) and (b) T < TKondo ≪ Twire. In the first regime the effective (renormalized) electron-electron interaction is smaller than the tunneling matrix element. In this ...
