Aspects of String Compactification
… addresses some interesting problems in string compactification relevant to phenomenology, especially cosmological models derived from string theory Most attention is drawn to stabilizing the moduli and discussing the cosmology solutions given the effective potential obtained from string …

Supersymmetric Backgrounds in string theory
… structure moduli, for a given background of type IIB string theory in the presence of flux in special cases. We introduce a way to compute the complex structure and axion dilaton moduli explicitly. In the second part, we discuss $(0,2)$ supersymmetric versions of some recent exotic …

Topics in Gauge/Gravity Duality
The gauge theory/gravity correspondence encompasses a variety of di_erent specific dualities. We investigate various topics in the context of Super–Yang- Mills/type IIB string theory and superconformal Chern-Simons-matter/type IIA string theory dualities. We carry out a rather extensive study of …

Obstacles to realizing Quintessence from String Theory
… quintessence models by flux compactification of type IIB string theory. We focus on Kähler moduli as candidates for the quintessence field and briefly comment on other approaches. The large hierarchies required for simultaneously describing quintessence and the standard model pose a major …

Topics in gauge/gravity duality
… years, the Anti-de Sitter (AdS)/Conformal Field Theory (CFT) correspondence and its generalization in the ideas of gauge/gravity duality have had a profound impact in our understanding of strongly interacting quantum field theories. Roughly speaking, the correspondence maps the degrees of freedom …

Spiky strings and the AdS/CFT correspondence
… we explore some aspects of semiclassical type IIB string theory on AdS3 × S1 and on pure AdS3 in the limit of large angular momentum S. We first focus on the integrability technique known as finite-gap formalism for strings in AdS3 × S1, leading to the definition of a hyperelliptic Riemann …

Duality and Models of Supersymmetry Breaking
… of instantons in a non-supersymmetric gauge theory obtained via a marginal deformation of N = 4 super Yang-Mills. This gauge theory is expected to be dual to type IIB string theory on a background that is the product of five-dimensional anti-de Sitter spacetime and a deformed five-sphere. By …
