CFT correlators and mapping class group averages
Iordanis Romaidis, Ingo Runkel
Mapping class group averages appear in the study of 3D gravity partition functions. In this paper, we work with 3D topological field theories to establish a bulk-boundary correspon…
Parity and Spin CFT with boundaries and defects
Ingo Runkel, Lóránt Szegedy, Gérard M. T. Watts
This paper is a follow-up to [arXiv:2001.05055] in which two-dimensional conformal field theories in the presence of spin structures are studied. In the present paper we define fou…
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…
Fermionic CFTs and classifying algebras
Ingo Runkel, Gerard M. T. Watts
We study fermionic conformal field theories on surfaces with spin structure in the presence of boundaries, defects, and interfaces. We obtain the relevant crossing relations, takin…
Spin from defects in two-dimensional quantum field theory
Sebastian Novak, Ingo Runkel
We build two-dimensional quantum field theories on spin surfaces starting from theories on oriented surfaces with networks of topological defect lines and junctions. The constructi…
Logarithmic bulk and boundary conformal field theory and the full centre construction
Ingo Runkel, Matthias R. Gaberdiel, Simon Wood
We review the definition of bulk and boundary conformal field theory in a way suited for logarithmic conformal field theory. The notion of a maximal bulk theory which can be non-de…
