Experimental String Field Theory [PDF]

open access: yesJournal of High Energy Physics, 2002
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 ...

Free Field Theory as a String Theory? [PDF]

open access: yesComptes Rendus. Physique, 2004
An approach to systematically implement open-closed string duality for free large $N$ gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganisation of the Feynman diagrams contributing to free field ...

Closed String Cohomology in Open String Field Theory [PDF]

open access: yesJournal of High Energy Physics, 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.

Causality in string field theory

open access: yesEurophysics 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.

THE SPACE OF STRING CONFIGURATIONS IN STRING FIELD THEORY [PDF]

open access: yesInternational Journal of Modern Physics A, 1990
In this paper we consider the set of maps from the interval [0, π] which constitute the argument of the functionals of a String Field Theory. We show that in order to correctly reproduce results of the dual model one has to include all square integrable functions in the functional integral, or Ω0 in terms of Sobolev spaces.

String theory in electromagnetic fields [PDF]

open access: yesJournal of High Energy Physics, 2003
A review of various aspects of superstrings in background electromagnetic fields is presented. Topics covered include the Born-Infeld action, spectrum of open strings in background gauge fields, the Schwinger mechanism, finite-temperature formalism and Hagedorn behaviour in external fields, Debye screening, D-brane scattering, thermodynamics of D ...

Mapping between Witten and lightcone string field theories

open access: yesJournal of High Energy Physics, 2021
We propose a transformation between the off-shell field variables of Witten’s open bosonic string field theory and the traditional lightcone string field theory of Kaku and Kikkawa, based on Mandelstam’s interacting string picture.

Aspects of Nonrelativistic Strings

open access: yesFrontiers in Physics, 2022
We review recent developments on nonrelativistic string theory. In flat spacetime, the theory is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global symmetries acting on the worldsheet fields.
