Mean string field theory: Landau-Ginzburg theory for 1-form symmetries
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 amplitudes from Moyal string field theory [PDF]
Physical Review D, 2003 We illustrate a basic framework for analytic computations of Feynman graphs using the Moyal star formulation of string field theory. We present efficient methods of computation based on (a) the monoid algebra in noncommutative space and (b) the conventional Feynman rules in Fourier space.

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.

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 ...

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.

INTERPOLATING STRING FIELD THEORIES [PDF]
Modern Physics Letters A, 1992 A minimal area problem imposing different length conditions on open and closed curves is shown to define a one-parameter family of covariant open-closed quantum string field theories. These interpolate from a recently proposed factorizable open-closed theory up to an extended version of Witten’s open string field theory capable of incorporating on ...

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.

Physics Reports, 1989 Abstract We present an account of string field theory which aims to introduce the reader to the important concepts of the subjects as well as to aid access to the literature. Light cone string theory is briefly reviewed, but the emphasis is on the covariant approach exploiting world sheet BRST invariance to define string field derivations ...

Classical open string amplitudes from boundary string field theory
Journal of High Energy Physics, 2019 We calculate the corrections to the open string BRST charge in boundary string field theory and show that the expansion coefficients agree with the perturbative S-matrix to all orders.

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.
