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…
Towards a classification of topological defects in sigma models
Roberta Angius, Stefano Giaccari
Given a surface, a supersymmetric non-linear K3 sigma model is the internal superconformal field theory (SCFT) in a six dimensional compactification of type IIA superstring on…
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,…
On Democratic String Field Theories
Stefano Giaccari, Michael Kroyter
We reexamine democratic open string field theories, namely, theories in which string fields are not constrained to a single picture number and picture changing is obtained as a gau…
