Hyperbolic geometry and closed bosonic string field theory. Part I. The string vertices via hyperbolic Riemann surfaces [PDF]
Journal of High Energy Physics, 2017 The main geometric ingredient of the closed string field theory are the string vertices, the collections of string diagrams describing the elementary closed string interactions, satisfying the quantum Batalian-Vilkovisky master equation.

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

Foliated field theory and string-membrane-net condensation picture of fracton order [PDF]
SciPost Physics, 2018 Foliated fracton order is a qualitatively new kind of phase of matter. It is similar to topological order, but with the fundamental difference that a layered structure, referred to as a foliation, plays an essential role and determines the mobility ...

Mapping between Witten and lightcone string field theories
Journal 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.

Heterotic and bosonic string amplitudes via field theory [PDF]
Journal of High Energy Physics, 2018 Previous work has shown that massless tree amplitudes of the type I and IIA/B superstrings can be dramatically simplified by expressing them as double copies between field-theory amplitudes and scalar disk/sphere integrals, the latter containing all the ...

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory [PDF]
Fortschritte der Physik, 2021 We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$ ‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes

String theory in electromagnetic fields [PDF]
Journal 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 ...

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 ...

Aspects of Nonrelativistic Strings
Frontiers 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.
