Open string field theory with stubs
Journal of High Energy Physics, 2023 There are various reasons why adding stubs to the vertices of open string field theory (OSFT) is interesting: the stubs can not only tame certain singularities and make the theory more well-behaved, but also the new theory shares a lot of similarities ...

Background field method for nonlinear sigma models in nonrelativistic string theory [PDF]
Journal of High Energy Physics, 2020 We continue the study of nonrelativistic string theory in background fields. Nonrelativistic string theory is described by a nonlinear sigma model that maps a relativistic worldsheet to a non-Lorentzian and non-Riemannian target space geometry, which is ...

Closed String Cohomology in Open String Field Theory [PDF]
JHEP 1107:022,2011, 2010 We show that closed string states in bosonic string field theory are encoded in the cyclic cohomology of cubic open string field theory (OSFT) which, in turn, classifies the deformations of OSFT. This cohomology is then shown to be independent of the open string background.

String field theory of noncritical strings [PDF]
Physics Letters B, 1993 We construct a string field Hamiltonian for a noncritical string theory with the continuum limit of the Ising model or its generalization as the matter theory on the worldsheet. It consists of only three string vertices as in the case for $c=0$. We also discuss a general consistency condition that should be satisfied by this kind of string field ...

Searching for continuous phase transitions in 5D SU(2) lattice gauge theory
Journal of High Energy Physics, 2021 We study the phase diagram of 5-dimensional SU(2) Yang-Mills theory on the lattice. We consider two extensions of the fundamental plaquette Wilson action in the search for the continuous phase transition suggested by the 4 + ϵ expansion.

Bootstrapping closed string field theory
Journal of High Energy Physics, 2023 The determination of the string vertices of closed string field theory is shown to be a conformal field theory problem solvable by combining insights from Liouville theory, hyperbolic geometry, and conformal bootstrap.

Causality in string field theory
Europhysics Letters, 2023 Abstract In this letter, we will investigate causality in string field theory using pp-wave light-cone gauge string field theory. We will generalise the Ramsey scheme to string field theory, and use it to analyze string field theoretical processes.

Closed string deformations in open string field theory. Part I. Bosonic string
Journal of High Energy Physics, 2021 This is the first of a series of three papers on open string field theories based on Witten star product deformed with a gauge invariant open/closed coupling.

Conformal defects from string field theory
Journal of High Energy Physics, 2021 Unlike conformal boundary conditions, conformal defects of Virasoro minimal models lack classification. Alternatively to the defect perturbation theory and the truncated conformal space approach, we employ open string field theory (OSFT) techniques to ...
