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…
More on stubs in open string field theory
Martin Schnabl, Georg Stettinger
We continue our analysis of open string field theory based on A-infinity-algebras obtained from Witten's theory by attaching stubs to the elementary vertex. Classical solutions of…
Closed string tachyon condensation revisited
Jaroslav Scheinpflug, Martin Schnabl
We consider condensation of nearly marginal matter tachyons in closed string field theory and observe that upon restricting to a subspace of states not containing the ghost dilaton…
Open string field theory with stubs
Martin Schnabl, Georg Stettinger
There are various reasons why adding stubs to the vertices of open string field theory (OSFT) is interesting: Not only the stubs can tame certain singularities and make the theory…
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…
Classical algebraic structures in string theory effective actions
Harold Erbin, Carlo Maccaferri, Martin Schnabl +1
We study generic properties of string theory effective actions obtained by classically integrating out massive excitations from string field theories based on cyclic homotopy algeb…
