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…
Gauge-invariant action for free string field theory with boundary
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We construct fully gauge-invariant kinetic terms for open and closed string field theories on a target space with boundary. This is realized by promoting the gauge parameters at th…
Boundary Modes in String Field Theory
Carlo Maccaferri, Riccardo Poletti, Alberto Ruffino +1
We discuss the construction of boundary contributions to free string field theory actions in the context of the bosonic string. We show that it is generally possible to obtain a we…
Bulk-induced D-brane deformations and the string coupling constant
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We consider computing the on-shell disk action of open-closed string field theory as a gauge-invariant way of capturing the shift in D-brane tension that is induced by a deformatio…
Topological defects and tensionless holography
Bob Knighton, Vit Sriprachyakul, Jakub Vošmera
We study topological defect lines in the symmetric-product orbifolds for a generic seed CFT . We focus on the defects which preserve the maximum of the …
Open-Closed String Field Theory in the Large Limit
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We use the new nilpotent formulation of open-closed string field theory to explore the limit where the number of identical D-branes of the starting background is large. By refo…
