Rotational Perturbations in Neveu-Schwarz–Neveu-Schwarz String Cosmology
First order rotational perturbations of the flat Friedmann-Robertson-Walker (FRW) metric are considered in the framework of four dimensional Neveu-Schwarz–Neveu-Schwarz (NS-NS) string cosmological models coupled with dilaton and axion fields. The decay rate of rotation depends mainly upon the dilaton field potential U . The equation for rotation imposes strong limitations upon the functional fo...
متن کاملAnisotropic four-dimensional Neveu-Schwarz–Neveu-Schwarz string cosmology
An anisotropic ~Bianchi type I! cosmology is considered in the four-dimensional Neveu-Schwarz–NeveuSchwarz ~NS–NS! sector of low-energy effective string theory coupled to a dilaton and an axionlike H field within a de Sitter–Einstein frame background. The general solution of the gravitational field equations can be expressed in an exact parametric form in both Einstein and string frames. The st...
متن کاملNeveu - Schwarz String Field Theory
A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of V = −
متن کاملNon-Abelian Ramond-Neveu-Schwarz String Theory
We construct a locally supersymmetric worldsheet formulation of a nonAbelian Ramond-Neveu-Schwarz (NARNS) string theory where the string coordinates are noncommuting matrices in a group U(N). This is described by the two dimensional supergravity coupled to supersymmetric Yang-Mills fields and adjoint matters in the gauge group U(N). We show that our NARNS string theory has a free string limit w...
متن کاملNeveu - Schwarz Five - Branes And Matrix String Theory On K
The Matrix theory description of Type IIA string theory on a compact K3 surface as the theory of Neveu-Schwarz five-branes oñ K3 × S 1 is analyzed. The full multiplet of space-time BPS states is identified in the five-brane world-volume as fluxes. October 1997
