Fixing an ambiguity in two dimensional string theory using string field theory [PDF]
Journal of High Energy Physics, 2020 In a recent paper, Balthazar, Rodriguez and Yin found some remarkable agreement between the results of c = 1 matrix model and D-instanton corrections in two dimensional string theory.

The closed string field theory action vanishes [PDF]
Journal of High Energy Physics, 2022 Using the dilaton theorem, we show that the classical action of closed string field theory vanishes on-shell.

String field theory as world-sheet UV regulator [PDF]
Journal of High Energy Physics, 2019 Even at tree level, the first quantized string theory suffers from apparent short distance singularities associated with collision of vertex operators that prevent us from straightforward numerical computation of various quantities.

Topological defects in open string field theory [PDF]
Journal of High Energy Physics, 2018 We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of Graham and Watts to include the action of defects on boundary condition ...

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 ...

Mean string field theory: Landau-Ginzburg theory for 1-form symmetries [PDF]
SciPost Physics, 2022 By analogy with the Landau-Ginzburg theory of ordinary zero-form symmetries, we introduce and develop a Landau-Ginzburg theory of one-form global symmetries, which we call mean string field theory.

String field theory solution for any open string background. Part II [PDF]
Journal of High Energy Physics, 2020 Generalizing previous work, we give a new analytic solution in Witten’s open bosonic string field theory which can describe any open string background. The central idea is to use Riemann surface degenerations as a mechanism for taming OPE singularities ...

D-instantons, string field theory and two dimensional string theory [PDF]
Journal of High Energy Physics, 2021 In [4] Balthazar, Rodriguez and Yin (BRY) computed the one instanton contribution to the two point scattering amplitude in two dimensional string theory to first subleading order in the string coupling.

String field theory solution for any open string background [PDF]
Journal of High Energy Physics, 2014 We present an exact solution of open bosonic string field theory which can be used to describe any time-independent open string background. The solution generalizes an earlier construction of Kiermaier, Okawa, and Soler, and assumes the existence of ...

Genus-one string amplitudes from conformal field theory [PDF]
Journal of High Energy Physics, 2019 We explore and exploit the relation between non-planar correlators in N $$ \mathcal{N} $$ = 4 super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory.
