Closed string deformations in open string field theory. Part II. Superstring
This is the second paper of a series of three. We construct effective open-closed superstring couplings by classically integrating out massive fields from open superstring field theories coupled to an elementary gauge invariant tadpole proportional to an

Background independence of closed superstring field theory
Given a family of world-sheet superconformal field theories related by marginal deformation, we can formulate superstring field theory based on any of these world-sheet theories.

Analytic solution for tachyon condensation in open string field theory [PDF]
We propose a new basis in Witten’s open string field theory, in which the star product simplifies considerably. For a convenient choice of gauge the classical string field equation of motion yields straightforwardly an exact analytic solution that ...

Local string field theory [PDF]
We consider open bosonic strings. The non-interacting multi-string theory is described by certain free string field operators which we construct. These are shown to have local commutators with respect to a center of mass coordinate. The construction is carried out both in the light cone gauge and in a covariant formulation.

Nonrelativistic string theory and T-duality
Nonrelativistic string theory in flat spacetime is described by a two-dimensional quantum field theory with a nonrelativistic global symmetry acting on the worldsheet fields. Nonrelativistic string theory is unitary, ultraviolet complete and has a string

Asymptotic scalar field cosmology in string theory
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 ...

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 ...

Multibrane solutions in open string field theory [PDF]
A bstractWe study properties of a class of solutions of open string field theory which depend on a single holomorphic function F (z). We show that the energy of these solutions is well defined and is given by integer multiples of a single D-brane tension.

String cosmology — Large-field inflation in string theory [PDF]
This is a short review of string cosmology. We wish to connect string-scale physics as closely as possible to observables accessible to current or near-future experiments. Our possible best hope to do so is a description of inflation in string theory. The energy scale of inflation can be as high as that of Grand Unification (GUT). If this is the case,

Winding number in string field theory [PDF]
A bstractMotivated by the similarity between cubic string field theory (CSFT) and the Chern-Simons theory in three dimensions, we study the possibility of interpreting $ \mathcal{N} = \left( {{\pi^2}/3} \right)\int {{{\left( {U{\mathcal{Q}_B}{U^{{ - 1}}}}
