Entanglement entropy plays a variety of roles in quantum field theory, including the
connections between quantum states and gravitation through the holographic principle. This …

A bstract Equilibrium finite temperature observables of a CFT can be described by a local
effective action for background fields—a “thermal effective action”. This effective action …

A bstract We study worldsheet instantons in holographic type IIA backgrounds directly in
string theory. The first background is a dimensional reduction of AdS 7× S 4 and is dual to …

The literature on the spectral analysis of second order elliptic differential operators contains
a great deal of information on the spectral functions for explicitly known spectra. The same is …

We compute the spectrum of light hadrons in a holographic dual of QCD defined on AdS 5×
S 5 which has conformal behavior at short distances and confinement at large interquark …

A bstract We study the rich dynamics resulting from introducing static charged particles
(Wilson lines) in 2+ 1 and 3+ 1 dimensional gauge theories. Depending on the charges of …

This thesis presents the state of the art in the study of Bondi-Metzner-Sachs (BMS) symmetry
and its applications in the simplified setting of three dimensions. It focuses on presenting all …

A bstract We explore analytical aspects of correlators involving Dirac spinors in d+ 1-
dimensional de Sitter space. Adapting the formalism of Sleight and Taronna, we show how …

A bstract We study line defects in the fermionic CFTs in the Gross-Neveu-Yukawa
universality class in dimensions 2< d< 4. These CFTs may be described as the IR fixed …

Logarithmic corrections to the entropy of extremal black holes have been successfully used
to accurately match degeneracies from microscopic constructions to calculations of the …
