Domain walls between 3d phases of Reshetikhin-Turaev TQFTs
Vincent Koppen, Vincentas Mulevicius, Ingo Runkel +1
We study surface defects in three-dimensional topological quantum field theories which separate different theories of Reshetikhin-Turaev type. Based on the new notion of a Frobeniu…
Bulk from boundary in finite CFT by means of pivotal module categories
Jürgen Fuchs, Christoph Schweigert
We present explicit mathematical structures that allow for the reconstruction of the field content of a full local conformal field theory from its boundary fields. Our framework is…
CFT Correlators for Cardy Bulk Fields via String-Net Models
Christoph Schweigert, Yang Yang
We show that string-net models provide a novel geometric method to construct invariants of mapping class group actions. Concretely, we consider string-net models for a modular tens…
Full Logarithmic Conformal Field theory - an Attempt at a Status Report
Jürgen Fuchs, Christoph Schweigert
Logarithmic conformal field theories are based on vertex algebras with non-semisimple representation categories. While examples of such theories have been known for more than 25 ye…
Boundary and Defect CFT: Open Problems and Applications
Natan Andrei, Agnese Bissi, Matthew Buican +18
Proceedings of the workshop "Boundary and Defect Conformal Field Theory: Open Problems and Applications," Chicheley Hall, Buckinghamshire, UK, 7-8 Sept. 2017.
Non-abelian gerbes and some applications in string theory
Christoph Schweigert, Konrad Waldorf
We review a systematic construction of the 2-stack of bundle gerbes via descent, and extend it to non-abelian gerbes. We review the role of non-abelian gerbes in orientifold sigma…
