RG Interfaces from Double-Trace Deformations
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study a class of interface conformal field theories obtained by taking a large CFT and turning on a relevant double-trace deformation over half space. At low energies, this…

Effective Field Theory of Conformal Boundaries
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proport…

Models with Boundary Interactions and their Long Range Generalizations
Simone Giombi, Himanshu Khanchandani
We study the critical properties of scalar field theories in dimensions with invariant interactions localized on a -dimensional boundary. By a combination of large…
