Kondo screening in a magnetically frustrated nanostructure: Exact results on a stable, non-Fermi-liquid phase
Kevin Ingersent, Andreas W. W. Ludwig, Ian Affleck
Triangular symmetry stabilizes a novel non-Fermi-liquid phase in the three-impurity Kondo model with frustrating antiferromagnetic interactions between half-integer impurity spins.…
Stochastic Loewner evolution for conformal field theories with Lie-group symmetries
E. Bettelheim, I. A. Gruzberg, A. W. W. Ludwig +1
The Stochastic Loewner evolution is a recent tool in the study of two-dimensional critical systems. We extend this approach to the case of critical systems with continuous symmetri…
Interaction Effects on Quasiparticle Localization in Dirty Superconductors
M. Jeng, A. W. W. Ludwig, T. Senthil +1
We study how quasiparticle interactions affect their localization properties in dirty superconductors with broken time reversal symmetry -- for example in a magnetic field. For SU(…
Separation of spin and charge in paired spin-singlet quantum Hall states
E. Ardonne, F. J. M. van Lankvelt, A. W. W. Ludwig +1
We propose a series of paired spin-singlet quantum Hall states, which exhibit a separation of spin and charge degrees of freedom. The fundamental excitations over these states, whi…
A Free Field Representation of the Osp(2|2) current algebra at level k=-2, and Dirac Fermions in a random SU(2) gauge potential
Andreas W. W. Ludwig
The Osp(2|2) current algebra at level k=-2 is known to describe the IR fixed point of 2D Dirac fermions, subject to a random SU(2) gauge potential. We show that this theory has a s…
Exact Zero Temperature Correlation Functions for Two-Leg Hubbard Ladders and Carbon Nanotubes
Robert Konik, Andreas W. W. Ludwig
Motivated by recent work of Lin, Balents, and Fisher (cond-mat/9801285), we compute correlation functions at zero temperature for weakly coupled two-leg Hubbard ladders and (N,N) a…
