2. 1. String Theory at the Horizon : Quantum Aspects of Black Holes and Cosmology

   Author : Martin Olsson; Ulf Danielsson; Lárus Thorlacius; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; black holes; cosmology; de Sitter space; c=1 matrix models; 2D string theory; topological string theory; conifolds; 4D BPS black holes; Gödel universe; closed time-like curves; Teoretisk fysik; Physics; Fysik;

   Abstract : String theory is a unified framework for general relativity and quantum mechanics, thus being a theory of quantum gravity. In this thesis we discuss various aspects of quantum gravity for particular systems, having in common the existence of horizons. READ MORE

5. 3. Degenerate Geometries, Supersymmetry and Duality

   Author : Henrik Gustafsson; Marcus Grisary; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

   Abstract : String theory is a theory attempting to unify gravity with the electro-weak and strong interactions so successfully described by Quantum Field Theory. The implications of String Theory is not fully understood since it is still not a complete theory. READ MORE
