Flowing with Displacements and Tilts: Surface Operators in Models
Jake Belton, Nadav Drukker, Biswajit Sahoo
Defect conformal field theories have special operators of protected dimension known as displacements and tilts. They arise due to the breaking of global symmetries by the defect an…

Crosscap Defects
Nadav Drukker, Shota Komatsu, Anders Wallberg
We introduce a novel class of defects, termed crosscap defects, in conformal field theory (CFT) in general dimensions. These arise from quotienting the spacetime by a automor…
