Competing effects of interactions and spin-orbit coupling in a quantum wire
V. Gritsev, G. I. Japaridze, M. Pletyukhov +1
We study the interplay of electron-electron interactions and Rashba spin-orbit coupling in one-dimensional ballistic wires. Using the renormalization group approach we construct th…
Incipient quantum melting of the one-dimensional Wigner lattice
S. Fratini, B. Valenzuela, D. Baeriswyl
A one--dimensional tight--binding model of electrons with long--range Coulomb interactions is studied in the limit where double site occupancy is forbidden and the Coulomb coupling…
Cohesion, Conductance, and Charging Effects in a Metallic Nanocontact
C. A. Stafford, F. Kassubek, J. Bürki +2
The conducting and thermodynamic properties of ballistic metallic nanocontacts with smooth shapes are investigated. All properties are related to the electronic scattering matrix,…
Variational Wave Function for Generalized Wigner Lattices in One Dimension
S. Fratini, B. Valenzuela, D. Baeriswyl
We study a system of electrons on a one-dimensional lattice, interacting through the long range Coulomb forces, by means of a variational technique which is the strong coupling ana…
Optical absorption edge in one-dimensional conductors
J. M. P. Carmelo, P. D. Sacramento, N. M. R. Peres +1
The frequency-dependent conductivity is studied for both the one-dimensional Hubbard model and a model of spinless fermions, using a selection rule, the Bethe ansatz energy eigenst…
Friedel transition in a modified XY model
M. Dzierzawa, M. Zamora, D. Baeriswyl +1
Weakly coupled superconducting layers are described by the three-dimensional XY model with strong coupling in two directions and weak coupling in the third direction. For the usual…
