Luttinger Liquid Behavior in Carbon Nanotubes
M. Bockrath, D. H. Cobden, J. Lu +4
An interacting one-dimensional (1D) electron system is predicted to behave very differently than its higher-dimensional counterparts. Coulomb interactions strongly modify the prope…
Dual Order Parameter for the Nodal Liquid
Leon Balents, Matthew Fisher, Chetan Nayak
The guiding conception of vortex-condensation-driven Mott insulating behavior is central to the theory of the nodal liquid. We amplify our earlier description of this idea and show…
Quasiparticle transport and localization in high-T_c superconductors
T. Senthil, Matthew P. A. Fisher, Leon Balents +1
We present a theory of the effects of impurity scattering in d_{x^2-y^2} superconductors and their quantum disordered counterparts, based on a non-linear sigma model formulation. W…
Nodal Liquid Theory of the Pseudo-Gap Phase of High-Tc Superconductors
Leon Balents, Matthew P. A. Fisher, Chetan Nayak
We introduce and study the nodal liquid, a novel zero-temperature quantum phase obtained by quantum-disordering a d-wave superconductor. It has numerous remarkable properties which…
Exact SO(8) Symmetry in the Weakly-Interacting Two-Leg Ladder
Hsiu-Hau Lin, Leon Balents, Matthew P. A. Fisher
A perturbative renormalization group analysis of interacting electrons on a two-leg ladder reveals that at half-filling any weakly repulsive system scales onto an exactly soluble G…
