Monodromy Pinning Defects in the Critical Model
Petr Kravchuk, Alex Radcliffe
We investigate a novel class of defects in the critical model that preserve conformal symmetry along the defect, but not the symmetry under rotations transverse to…
Bounds on Abelian Currents in 4d CFTs
Denis Karateev, Petr Kravchuk, Andrea Manenti +2
We study four-dimensional conformal field theories (CFTs) with an abelian global symmetry using the conformal bootstrap approach. We obtain numerical bounds on the scaling d…
Nonlinearly Realised Defect Symmetries and Anomalies
Nadav Drukker, Ziwen Kong, Petr Kravchuk
Conformal defects -- extended objects in conformal field theories -- carry localised excitations inherited from symmetry currents, known as the displacements and tilts. They captur…
Effective theory for fusion of conformal defects
Petr Kravchuk, Alex Radcliffe, Ritam Sinha
We construct an effective field theory for fusion of conformal defects of any codimension in conformal field theories. We fully solve the constraints of Weyl invariance f…
