Towards a Field Theory of the Plateau Transition
M. J. Bhaseen, I. I. Kogan, O. A. Soloviev +2
We suggest a procedure for calculating correlation functions of the local densities of states (DOS) at the plateau transitions in the Integer Quantum Hall effect (IQHE). We argue t…
Dual Response Models for the Fractional Quantum Hall Effect
L. Cooper, I. I. Kogan, A. Lopez +1
It is shown that the Jain mapping between states of integer and fractional quantum Hall systems can be described dynamically as a perturbative renormalization of an effective Chern…
Skyrmions in the quantum Hall effect at finite Zeeman coupling
A. G. Green, I. I. Kogan, A. M. Tsvelik
Using a self consistent approximation for the spin distribution of Skyrmions in the quantum Hall effect, we obtain an effective action for the Skyrmion coordinates. The energy func…
The Liouville Theory as a Model for Prelocalized States in Disordered Conductors
Ian. I. Kogan, C. Mudry, A. M. Tsvelik
It is established that the distribution of the zero energy eigenfunctions of (2 + 1)-dimensional Dirac electrons in a random gauge potential is described by the Liouville model. Th…
Skyrmion Liquid in SU(2)-invariant Quantum Hall Systems
A. G. Green, I. I. Kogan, A. M. Tsvelik
We report on a theory of the Skyrmion states which occur in quantum Hall regime near certain filling factors. It is shown that in the limit of zero Zeeman splitting in a realistic…
Investigations of Pairing in Anyon Systems
M. I. Dobroliubov, I. I. Kogan, G. W. Semenoff
We investigate pairing instabilities in the Fermi-liquid-like state of a single species of anyons. We describe the anyons as Fermions interacting with a Chern-Simons gauge field an…
