Observables of boundary RG flows from string field theory
Jaroslav Scheinpflug, Martin Schnabl, Jakub Vošmera
We present simple explicit formulae for the change of the -function, boundary state, boundary spectrum and structure constants between the endpoints of short boundary RG flows a…

Conformal perturbation theory from open string field theory
Jaroslav Scheinpflug, Martin Schnabl
Conformal boundary conditions in two-dimensional conformal field theories are still mostly an uncharted territory. Even less is known about the relevant boundary deformations that…
