Luttinger Liquid in the Core of a Screw Dislocation in Helium-4
Monte carlo simulation hexagonal shaft screw crystals superfluids screw dislocation
2014/12/20
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...
Universal Luttinger Liquid Relations in the 1D Hubbard Model
Luttinger Liquid Relations 1D Hubbard Model Strongly Correlated Electrons
2011/7/25
Abstract: We study the 1D extended Hubbard model with a weak repulsive short-range interaction in the non-half-filled band case, using non-perturbative Renormalization Group methods and Ward Identitie...
Effect of electron-phonon coupling on transmission through Luttinger liquid hybridized with resonant level
Effect of electron-phonon Luttinger liquid hybridized resonant level
2010/11/23
We show that electron-phonon coupling strongly a ects transport properties of the Luttinger
liquid hybridized with a resonant level. Namely, this coupling signi cantly modi es the e ective energy-dep...
Electronic States and Superconducting Transition Temperature based on the Tomonaga-Luttinger liquid in Pr$_{2}$Ba$_{4}$Cu$_{7}$O$_{15-\delta}$
Pr2Ba4Cu7O15− first-principles calculations CuO double chain superconductivity
2010/11/17
An NQR experiment revealed superconductivity of Pr2Ba4Cu7O15− (Pr247) to be realized
on CuO double chain layers and suggests possibility of novel one-dimensional(1D) superconduc-
tivity. To c...
Conductance of Tomonaga-Luttinger liquid wires and junctions with resistances
Tomonaga-Luttinger liquid wires junctions with resistances
2010/11/25
We study the effect that resistive regions have on the conductance of a quantum wire with interacting electrons which is connected to Fermi liquid leads. Using the bosonization formalism and a Rayleig...
