An RG potential for the quantum Hall effects
J. Nissinen, C. A. Lütken
The phenomenological analysis of fully spin-polarized quantum Hall systems, based on holomorphic modular symmetries of the renormalization group (RG) flow, is generalized to more c…
Experimental probes of emergent symmetries in the quantum Hall system
C. A. Lütken, G. G. Ross
Experiments studying renormalization group flows in the quantum Hall system provide significant evidence for the existence of an emergent holomorphic modular symmetry . We…
On the origin of duality in the quantum Hall system
C. A. Lütken, G. G. Ross
We discuss the possible origin of the duality observed in the quantum Hall current-voltage characteristics. We clarify the difference between "particle-vortex" (complex modular) du…
Boundary Fixed Points, Enhanced Gauge Symmetry and Singular Bundles on K3
J. Fuchs, P. Kaste, W. Lerche +3
We investigate certain fixed points in the boundary conformal field theory representation of type IIA D-branes on Gepner points of K3. They correspond geometrically to degenerate b…
D-Branes on ALE Spaces and the ADE Classification of Conformal Field Theories
W. Lerche, A. Lutken, C. Schweigert
The spectrum of D2-branes wrapped on an ALE space of general ADE type is determined, by representing them as boundary states of N=2 superconformal minimal models. The stable quantu…
D-Branes on K3-Fibrations
P. Kaste, W. Lerche, C. A. Lutken +1
B-type D-branes are constructed on two different K3-fibrations over IP_1 using boundary conformal field theory at the rational Gepner points of these models. The microscopic CFT ch…
