Integrable deformations of CFTs and the discrete Hirota equations
Werner Nahm, Sinéad Keegan
We solve the discrete Hirota equations (Kirillov-Reshetikhin Q-systems) for , and their analogue for , for the cases where the second variable ranges over either a finite…
Conformal Field Theory and Torsion Elements of the Bloch Group
Werner Nahm
We argue that rational conformally invariant quantum field theories in two dimensions are closely related to torsion elements of the algebraic K-theory group K_3(C). If such a theo…
Localisation of Fermions to brane: Codimension
W. Nahm, D. H. Tchrakian
We investigate dimensional fermionic models in which the system in codimension- supports a topologically stable solution, and in which the fermion may be localised to the…
Mirror Symmetry on Kummer Type K3 Surfaces
Werner Nahm, Katrin Wendland
We investigate both geometric and conformal field theoretic aspects of mirror symmetry on N=(4,4) superconformal field theories with central charge c=6. Our approach enables us to…
A Hiker's Guide to K3 - Aspects of N=(4,4) Superconformal Field Theory with central charge c=6
W. Nahm, K. Wendland
We study the moduli space of N=(4,4) superconformal field theories with central charge c=6. After a slight emendation of its global description we find the locations of…
The associative algebras of conformal field theory
David Brungs, Werner Nahm
Modulo the ideal generated by the derivative fields, the normal ordered product of holomorphic fields in two-dimensional conformal field theory yields a commutative and associative…
On the Seiberg-Witten Approach to electric-magnetic Duality
Werner Nahm
Electric-magnetic duality allows to calculate the central charges of N=2 supersymmetric theories with massless hypermultiplets as derivatives of simple modular forms. The procedure…
Quasi-rational fusion products
Werner Nahm
Fusion is defined for arbitrary lowest weight representations of -algebras, without assuming rationality. Explicit algorithms are given. A category of quasirational representati…
Dilogarithm Identities in Conformal Field Theory
W. Nahm, A. Recknagel, M. Terhoeven
Dilogarithm identities for the central charges and conformal dimensions exist for at least large classes of rational conformally invariant quantum field theories in two dimensions.…
