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.

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.

Experimental string field theory [PDF]
Journal of High Energy Physics, 2003 We develop efficient algorithms for level-truncation computations in open bosonic string field theory. We determine the classical action in the universal subspace to level (18,54) and apply this knowledge to numerical evaluations of the tachyon condensate string field. We obtain two main sets of results.

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.

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 ...

Fixing an ambiguity in two dimensional string theory using string field theory
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.

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 ...
