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…
Transport through Quantum Dots: Analytic Results from Integrability
Robert Konik, Hubert Saleur, Andreas Ludwig
Recent experiments have probed quantum dots through transport measurements in the regime where they are described by a two lead Anderson model. In this paper we develop a new metho…
Thermal metal in network models of a disordered two-dimensional superconductor
J. T. Chalker, N. Read, V. Kagalovsky +3
We study the universality class for localization which arises from models of non-interacting quasiparticles in disordered superconductors that have neither time-reversal nor spin-r…
Interplay of the Scaling Limit and the Renormalization Group: Implications for Symmetry Restoration
Robert M. Konik, Hubert Saleur, Andreas W. W. Ludwig
Symmetry restoration is usually understood as a renormalization group induced phenomenon. In this context, the issue of whether one-loop RG equations can be trusted in predicting s…
Absence of a metallic phase in random-bond Ising models in two dimensions: applications to disordered superconductors and paired quantum Hall states
N. Read, Andreas W. W. Ludwig
When the two-dimensional random-bond Ising model is represented as a noninteracting fermion problem, it has the same symmetries as an ensemble of random matrices known as class D.…
Random-bond Ising model in two dimensions, the Nishimori line, and supersymmetry
Ilya A. Gruzberg, N. Read, Andreas W. W. Ludwig
We consider a classical random-bond Ising model (RBIM) with binary distribution of bonds on the square lattice at finite temperature. In the phase diagram of this model the…
