Non-minimal quasi-holes and topological degeneracy of FQHE
Riccardo Bergamin
We extend the analysis of the Vafa SUSY model of FQHE and discuss other observables which characterize the FQHE topological order. We consider in particular the bra…
FQHE and geometry
Riccardo Bergamin, Sergio Cecotti
Cumrun Vafa has proposed a microscopic description of the Fractional Quantum Hall Effect (FQHE) in terms of a many-body Hamiltonian invariant under four supersymmetries. The no…
FQHE and geometry
Riccardo Bergamin
Cumrun Vafa proposed a new unifying model for the principal series of FQHE which predicts non-Abelian statistics of the quasi-holes. The many-body Hamiltonian supporting these topo…
Geometry of Modular Curves
Riccardo Bergamin
Motivated by Vafa's model, we study the geometry of a degenerate class of FQHE models with an abelian group of symmetry acting transitively on the classical vacua. Despite…
Heat kernels on cone of and -wound circular Wilson loop in superstring
R. Bergamin, A. A. Tseytlin
We compute the one-loop world-sheet correction to partition function of superstring that should be representing -fundamental circular Wilson loop in planar li…
