Gauged Knizhnik-Zamolodchikov equation
I. I Kogan, A. Lewis, O. A. Soloviev
Correlation functions of gauged WZNW models are shown to satisfy a differential equation, which is a gauge generalization of the Knizhnik-Zamolodchikov equation.
Gravitational Dressing of Aharonov-Bohm Amplitudes
G. Amelino-Camelia, I. I. Kogan, R. J. Szabo
We investigate Aharonov-Bohm scattering in a theory in which charged bosonic matter fields are coupled to topologically massive electrodynamics and topologically massive gravity. W…
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…
