We show that the large-N limits of certainconformal field theories in various dimensions includein their Hilbert space a sector describing supergravityon the product of anti-de Sitter spacetimes, spheres, and other compact manifolds. This is shown bytaking some branes in the full M/string theory and thentaking a low-energy limit where the field theory on thebrane decouples from the bulk. We observe that, in this limit, we can still trust thenear-horizon geometry for large N. The… 

Black Holes , Branes and Superconformal Symmetry 1

The main focus of this lecture is on extended objects in adSp+2×Sd−p−2 bosonic backgrounds with unbroken supersymmetry. The backgrounds are argued to be exact, special consideration are given to the

Superconformal Chern-Simons Theories and Their String Theory Duals

In this thesis, we consider two aspects of the conjectured gauge theory/string theory correspondence between three-dimensional maximal supersymmetric conformal field theories, which describe the

Superconformal symmetry, supergravity and cosmology

We introduce the general N = 1 gauge theory superconformally coupled to supergravity. The theory has local SU(2,2|1) symmetry and no dimensional parameters. The superconformal origin of the

Aspects of Compactifications and Black Holes in Four-Dimensional Supergravity

In the 20th century, theoretical physics has seen the development of General Relativity and the Standard Model of elementary particles. These theories describe, with great precision, gravity and all

Heterotic and M-theory Compactifications for String Phenomenology

In this thesis, we explore two approaches to string phenomenology. In the first half of the work, we investigate M-theory compactifications on spaces with co-dimension four, orbifold singularities.

Supergravity and The Large N Limit of Theories With Sixteen Supercharges

We consider field theories with sixteen supersymmetries, which include U(N) Yang-Mills theories in various dimensions, and argue that their large N limit is related to certain supergravity solutions.

Quantum aspects of gauge theories , supersymmetry and unification

This is an introductory review of the AdS/CFT correspondence and of the ideas that led to its formulation. We show how comparison of stacks of D3-branes with corresponding supergravity solutions

Exact Results in Supersymmetric Quantum Field Theory

This thesis is devoted to a number of exact computations in various supersymmetric quantum field theories and their applications in studying nonperturbative properties of the theories. In the first


In this thesis, we present two current topics in theoretical high energy physics: We construct the Lagrangian of a deformed supergravity theory on a manifold with a non-trivial spacetime boundary by



Universal low-energy dynamics for rotating black holes

Fundamental string theory has been used to show that low-energy excitations of certain black holes are described by a two-dimensional conformal field theory. This picture has been found to be

Entropy and temperature of black 3-branes.

We consider slightly nonextremal black 3-branes of type IIB supergravity and show that their Bekenstein-Hawking entropy agrees, up to a mysterious factor, with an entropy derived by counting non-BPS
