N=2 Supersymmetry and Bailey Pairs
Alexander Berkovich, Barry M. McCoy, Anne Schilling
We demonstrate that the Bailey pair formulation of Rogers-Ramanujan identities unifies the calculations of the characters of and supersymmetric conformal field theories…
Supersymmetric sigma-models, twistors, and the Atiyah-Hitchin metric
I. T. Ivanov, M. Rocek
The Legendre transform and its generalizations, originally found in supersymmetric sigma-models, are techniques that can be used to give constructions of hyperkahler metrics. We gi…
Determinant representation for a quantum correlation function of the lattice sine-Gordon model
Fabian H. L. Essler, Holger Frahm, Alexander R. Its +1
We consider a completely integrable lattice regularization of the sine-Gordon model with discrete space and continuous time. We derive a determinant representation for a correlatio…
Poisson-Lie T-Duality: the Path-Integral Derivation
Eugene Tyurin, Rikard von Unge
We formulate Poisson-Lie T-duality in a path-integral manner that allows us to analyze the quantum corrections. Using the path-integral, we rederive the most general form of a Pois…
Cancellation of quantum mechanical higher loop contributions to the gravitational chiral anomaly
Andrew K. Waldron
We give an explicit demonstration, using the rigorous Feynman rules developed in~$\0^{1}$, that the regularized trace $\tr γ_5 e^{-β\Dslash^2}$ for the gravitational chiral anomaly…
Nonabelian Gauge Symmetry in the Causal Epstein-Glaser Approach
Tobias Hurth
We present some generalizations of a recently proposed alternative approach to nonabelian gauge theories based on the causal Epstein-Glaser method in perturbative quantum field the…
