Fusion of conformal defects in four dimensions
Alexander Söderberg
We consider two conformal defects close to each other in a free theory, and study what happens as the distance between them goes to zero. This limit is the same as zooming out, and…
On Analytic Bootstrap for Interface and Boundary CFT
Parijat Dey, Alexander Söderberg
We use analytic bootstrap techniques for a CFT with an interface or a boundary. Exploiting the analytic structure of the bulk and boundary conformal blocks we extract the CFT data.…
Composite operators near the boundary
Vladimír Procházka, Alexander Söderberg
We use renormalization group methods to study composite operators existing at a boundary of an interacting conformal field theory. In particular we relate the data on boundary oper…
Analytic Bootstrap for Boundary CFT
Agnese Bissi, Tobias Hansen, Alexander Söderberg
We propose a method to analytically solve the bootstrap equation for two point functions in boundary CFT. We consider the analytic structure of the correlator in Lorentzian signatu…
