Titre | Fusion of conformal interfaces and bulk induced boundary RG flows |
Résumé | We will consider the free massless compact boson in two dimensions focusing on the basic radius-changing conformal interface. After investigating different theoretical aspects of this object we will discuss the fusion of this interface with conformal boundary conditions. At fractions of the self-dual radius there exist exceptional conformal boundary conditions (D-branes). It was argued by Fredenhagen, Gaberdiel and Keller that changing the radius in the bulk induces a boundary RG flow. Following Brunner and Roggenkamp we conjecture that fusing the basic radius changing interface (that changes the radius from a fraction of the self-dual radius) with the exceptional boundary conditions gives the boundary condition which is the end point of the RG flow at hand. By studying the fusion singularities we recover RG logarithms and see, in particular instances, how they get resummed into power singularities. We discuss what quantities need to be calculated to gain full non- perturbative control over the fusion. |
