Closed string cohomology in open string field theory [PDF]
Journal of High Energy Physics, 2011 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. This cohomology is then shown to be independent of the open string background.

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.

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.

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 ...

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.

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.

NONCOMMUTATIVE FIELD THEORIES AND (SUPER)STRING FIELD THEORIES [PDF]
Particles and Fields, 2002 In this lecture notes we explain and discuss some ideas concerning noncommutative geometry in general, as well as noncommutative field theories and string field theories. We consider noncommutative quantum field theories emphasizing an issue of their renormalizability and the UV/IR mixing. Sen's conjectures on open string tachyon condensation and their

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 ...
