A Renormalisation group for TCSA
Giovanni Feverati, Kevin Graham, Paul A. Pearce +2
We discuss the errors introduced by level truncation in the study of boundary renormalisation group flows by the Truncated Conformal Space Approach. We show that the TCSA results c…
On the time-dependent description for the decay of unstable D-branes
Kevin Graham, Anatoly Konechny, Joerg Teschner
We discuss how to describe time-dependent phenomena in string theory like the decay of unstable D-branes with the help of the world-sheet formulation. It is shown in a nontrivial w…
Defect Lines and Boundary Flows
K. Graham, G. M. T. Watts
Using the properties of defect lines, we study boundary renormalisation group flows. We find that when there exists a flow between maximally symmetric boundary conditions "a" and "…
On Perturbations of Unitary Minimal Models by Boundary Condition Changing Operators
K. Graham
In this note we consider boundary perturbations in the A-Series unitary minimal models by phi_{r,r+2} fields on superpositions of boundaries. In particular, we consider perturbatio…
Minimal model boundary flows and c=1 CFT
K. Graham, I. Runkel, G. M. T Watts
We consider perturbations of unitary minimal models by boundary fields. Initially we consider the models in the limit as c -> 1 and find that the relevant boundary fields all have…
