Cosmological Quantum String Vacua and String-String Duality
نویسندگان
چکیده
Implications of string-string dualities to cosmological string vacua are discussed. Cosmological vacua of classical string theories comprise of disjoint classses mapped one another by scale-factor T-duality. Each classes are, however, afflicted with initial/final cosmological singularities. It is argued that quantum string theories and string-string dualities dramatically resolve these cosmological singularities out so that disjoint classical cosmological vacua are continuously connected in a unified manner. A natural inflationary cosmology follows from this. † Invited talk given at the Fourth International Conference on Supersymmetry (SUSY ’96), College Park, May 26 June 1, 1996; To be published in the proceedings.

String Phenomenology: Past, Present and Future Perspectives
The observation of a scalar resonance at the Large Hadron Collider (LHC), compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model (SM) parameterisation of all subatomic data. The logarithmic evolution of the SM gauge and matter parameters suggests that this parameterisation remains viable up to the Planck scale, where gravitational effects are of comparable str...
متن کاملBulk viscous string cosmological models in Saez – Ballester theory of gravitation
Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating...
متن کاملTime–dependent Orbifolds and String Cosmology
In these lectures, we review the physics of time–dependent orbifolds of string theory, with particular attention to orbifolds of three–dimensional Minkowski space. We discuss the propagation of free particles in the orbifold geometries, together with their interactions. We address the issue of stability of these string vacua and the difficulties in defining a consistent perturbation theory, poi...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کامل4d Conformal Field Theories and Strings on Orbifolds
We propose correspondences between 4d quantum field theories with N = 2, 1, 0 (super)conformal invariance and Type IIB string theory on various orbifolds of AdS 5 × S 5. We argue using the spacetime string theory, and check using the beta functions (exactly for N = 2, 1 and so far at 1-loop for the gauge couplings in the N = 0 case), that these theories have conformal fixed lines. The latter ca...
