Non-invertible defects from the Conway SCFT to K3 sigma models II: duality and Fibonacci defects
Roberta Angius, Stefano Giaccari, Sarah M. Harrison +1
We continue the study, initiated in [hep-th:2504.18619], of topological defect lines (TDLs) in the Conway module and K3 non-linear sigma models (NLSMs). In the cas…

Non-invertible defects from the Conway SCFT to K3 sigma models I: general results
Roberta Angius, Stefano Giaccari, Sarah M. Harrison +1
We initiate the study of supersymmetry-preserving topological defect lines (TDLs) in the Conway moonshine module . We show that the tensor category of such defects,…

Liouville theory and the Weil-Petersson geometry of moduli space: bordered, conic, and higher genus surfaces
Kale Colville, Sarah M. Harrison, Alexander Maloney +1
Two-dimensional conformal field theory is a powerful tool to understand the geometry of surfaces. Here, we study Liouville conformal field theory in the classical (large central ch…
