Explorations of four and five dimensional black hole spacetimes [PDF]
, 2009 This thesis concentrates on four and five dimensional black holes and their associated geodesies. Some coordinate charts are presented, which are useful in the analysis of both static and rotating black holes, and their mathematical properties ...

A Lightning Introduction to String Theory [PDF]
We give a lightning introduction to critical string theory, including the 26-dimensional bosonic string, the 10-dimensional superstrings and heterotic strings with and without spacetime supersymmetry. We also discuss open strings and D-branes, as well as

TWO-LOOP VACUUM ENERGY For Calabi-Yau Orbifold Models [PDF]
, 2013 A precise evaluation of the two-loop vacuum energy is provided for certain Z2×Z2 Calabi-Yau orbifold models in the Heterotic string. The evaluation is based on the recent general prescription for superstring perturbation theory in terms of integra-tion ...

The dynamics of cosmological scenarios inspired by quantum gravity [PDF]
, 2006 PhDIn this thesis we study the dynamics of cosmological scenarios inspired by quantum gravity. Part I investigates novel features of the semi-classical regime of homogeneous and isotropic loop quantum cosmology.

Attraction to a radiation-like era in early superstring cosmologies [PDF]
, 2009 38 pages, 4 figuresStarting from an initial classical four dimensional flat background of the heterotic or type II superstrings, we are able to determine at the string one-loop level the quantum corrections to the effective potential due to the ...

Cartan geometry, supergravity and group manifold approach [PDF]
summary:We make a case for the unique relevance of Cartan geometry for gauge theories of gravity and supergravity. We introduce our discussion by recapitulating historical threads, providing motivations.

Higher-dimensional black holes: Braneworld stars and Hawking radiation. [PDF]
, 2007 In this thesis two aspects of braneworld models are studied. A new attempt at finding the metric of a braneworld black hole within the second Randall-Sundrum model is explored. Branes containing distributions of perfect fluid are embedded in a variety of

String theory in the early universe [PDF]
, 2009 String theory is a rich and elegant framework which many believe furnishes a UV-complete unified theory of the fundamental interactions, including gravity.
