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…
Mirror Maps in Chern-Simons Gauge Theory
L. Cooper, I. I. Kogan, R. J. Szabo
We describe mirror symmetry in N=2 superconformal field theories in terms of a dynamical topology changing process of the principal fiber bundle associated with a topological membr…
Dynamical Description of Spectral Flow in N=2 Superconformal Field Theories
Leith Cooper, Ian I. Kogan, Richard J. Szabo
We show how the spectral flow between the Neveu-Schwarz and Ramond sectors of N=2 superconformal field theories can be described in three dimensions in terms of the propagation of…
String Winding Modes From Charge Non-Conservation in Compact Chern-Simons Theory
Leith Cooper, Ian I. Kogan, Kai-Ming Lee
In this letter we show how string winding modes can be constructed using topological membranes. We use the fact that monopole-instantons in compact topologically massive gauge theo…
Boundary Conditions and Heterotic Construction in Topological Membrane Theory
Leith Cooper, Ian I. Kogan
Using the topological membrane approach to string theory, we suggest a geometric origin for the heterotic string. We show how different membrane boundary conditions lead to differe…
