The Evaluation of Graphs on Surfaces for State-Sum Models with Defects
Julian Farnsteiner, Christoph Schweigert
The evaluation of graphs on 2-spheres is a central ingredient of the Turaev-Viro construction of three-dimensional topological field theories. In this article, we introduce a class…
Topological defects for the free boson CFT
Jürgen Fuchs, Matthias R. Gaberdiel, Ingo Runkel +1
Two different conformal field theories can be joined together along a defect line. We study such defects for the case where the conformal field theories on either side are single f…
Duality and defects in rational conformal field theory
Jürg Fröhlich, Jürgen Fuchs, Ingo Runkel +1
We study topological defect lines in two-dimensional rational conformal field theory. Continuous variation of the location of such a defect does not change the value of a correlato…
Picard groups in rational conformal field theory
Jürg Fröhlich, Jürgen Fuchs, Ingo Runkel +1
Algebra and representation theory in modular tensor categories can be combined with tools from topological field theory to obtain a deeper understanding of rational conformal field…
Solitonic sectors, alpha-induction and symmetry breaking boundaries
J. Fuchs, C. Schweigert
We develop a systematic approach to boundary conditions that break bulk symmetries in a general way such that left and right movers are not necessarily connected by an automorphism…
The geometry of WZW branes
G. Felder, J. Fröhlich, J. Fuchs +1
The structures in target space geometry that correspond to conformally invariant boundary conditions in WZW theories are determined both by studying the scattering of closed string…
