String field theory vertex from integrability [PDF]
, 2015 A bstractWe propose a framework for computing the (light cone) string field theory vertex in the case when the string worldsheet QFT is a generic integrable theory.

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.

Split string field theory I [PDF]
Journal of High Energy Physics, 2001 We describe the ghost sector of cubic string field theory in terms of degrees of freedom on the two halves of a split string. In particular, we represent a class of pure ghost BRST operators as operators on the space of half-string functionals. These BRST operators were postulated by Rastelli, Sen, and Zwiebach to give a description of cubic string ...

String scattering amplitudes and deformed cubic string field theory
Physics Letters B, 2018 We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge.

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
Journal of High Energy Physics, 2022 We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using string field theory.

String theory or field theory? [PDF]
Physics-Uspekhi, 2002 The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are discussed. This analysis helps better understand the role and place of string theory in the modern picture of the physical world.

Temporal-gauge String Field with Open Strings [PDF]
Phys.Lett. B351 (1995) 439-444, 1994 A string field theory including open string fields is constructed in the temporal gauge. It consists of string interaction vertices similar to the light-cone gauge string field theory. A slight modification of the definition of the time coordinate is needed because of the existence of the open string end points.

A simple solution for marginal deformations in open string field theory [PDF]
, 2014 A bstractWe derive a new open string field theory solution for boundary marginal deformations generated by chiral currents with singular self-OPE. The solution is algebraically identical to the Kiermaier-Okawa-Soler solution and it is gauge equivalent to

Dynamics of perturbations in Double Field Theory & non-relativistic string theory [PDF]
, 2015 A bstractDouble Field Theory provides a geometric framework capable of describing string theory backgrounds that cannot be understood purely in terms of Riemannian geometry — not only globally (‘non-geometry’), but even locally (‘non-Riemannian’).

Asymptotic scalar field cosmology in string theory
Journal of High Energy Physics, 2022 Asymptotic (late-time) cosmology depends on the asymptotic (infinite-distance) limits of scalar field space in string theory. Such limits feature an exponentially decaying potential V ~ exp(−cϕ) with corresponding Hubble scale H ~ ϕ ̇ 2 + 2 V $$ \sqrt ...
