Abelian ChernSimons theory with toral gauge group, modular tensor categories, and group categories
(200808)Classical and quantum ChernSimons with gauge group U(1)N were classified by Belov and Moore in [BM05]. They studied both ordinary topological quantum field theories as well as spin theories. On the other hand a correspondence ... 
Nonsupersymmetric holographic engineering and Uduality
(201208)In this Ph.D. thesis, we construct and study a number of new type IIB supergravity backgrounds that realize various flavored, finite temperature, and nonsupersymmetric deformations of the resolved and deformed conifold ... 
The philosophical significance of unitarily inequivalent representations in quantum field theory
(200805)This dissertation gives a general account of the properties of unitarily inequivalent representations (UIRs) in both canonical quantum field theory and algebraic quantum field theory. A simple model is constructed and then ... 
Spin TQFTs and ChernSimons gauge theory
(200405) 
State sums in two dimensional fully extended topological field theories
(201105)A state sum is an expression approximating the partition function of a ddimensional field theory on a closed dmanifold from a triangulation of that manifold. To consider state sums in completely local 2dimensional ... 
Suppression of radiation damping in electromagnetic waveguide, signature of quantum decoherence in the field bath
(2003)Recent development of spectral analysis of the Liouvillevon Neumann equation has revealed the fact that irreversibility is a rigorous dynamical property of Poincaré nonintegrable systems with an infinite degrees of ... 
Tinkertoys for Gaiotto duality
(201108)We describe a procedure for classifying 4D N=2 superconformal theories of the type introduced by Davide Gaiotto. Any punctured curve, C, on which the 6D (2,0) SCFT is compactified, may be decomposed into 3punctured spheres, ...
