Numerical implementations of holographic duality via the fluid/gravity correspondence
The fluid/gravity correspondence describes an map from relativistic fluid dynamics to general relativity in an anti de Sitter (AdS) background in one more dimension. This is a specific example of a more general principle known as holographic duality, in which a quantum field theory (QFT) is dual to …

From Quantum Information to Cosmic Censorship: Emergent Spacetimes and Their Surfaces
… gravity from the perspective of the AdS/CFT correspondence. We leverage global methods in General Relativity (GR) together with quantum information- and complexity-theoretic properties of the conformal field theory (CFT) dual to obtain novel results in classical and semiclassical …

Nonperturbative dynamics of strong interactions from gauge/gravity duality
… Quantum Chromodynamics (QCD) is a theory which describes strong interactions. For large energies, one can apply perturbative techniques to solve some of the QCD problems. However, for low energies QCD enters into the nonperturbative regime, where different analytical or numerical tools have to …

Topics in gauge/gravity duality
"Over the past 14 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 …

Aspects of finite temperature field theories in Ads/CFT
… field theories at finite temperature using the AdS/CFT correspondence. I present a general proof of an "inheritance principle" satisfied by a weakly coupled SU(N) (or U(N)) gauge theory with adjoint matter on a class of compact manifolds (like S3). In the large N limit, finite temperature …

Perturbations and symmetry in gravitational theories : wormholes, wave dynamics, and quantum effects in rotating spacetimes.
This dissertation develops a symmetry-centered framework for gravitational perturbation theory, applying it to linearized gravity and horizonless rotating space-times. The central thesis is that gauge invariance and geometric symmetry provide a unifying language for identifying physical degrees of …

Numerical Construction of Gravitational Solutions in Asymptotically Anti-de Sitter Spacetimes
Asymptotically anti-de Sitter (AdS) spacetimes display intriguing phenomena which have recently sparked increasing interest in the research of gravitational solutions in these spaces. Considerable motivation stems from gauge/gravity duality, which is a conjecture relating classical gravity with a …

Disorder in holographic field theories: inhomogeneous geometries, momentum relaxation and SYK models
… translational symmetry are still poorly understood in this context. In this dissertation, we investigate three new approaches to this challenging problem. The first part of the dissertation concerns a class of phenomenological holographic models in which momentum relaxation can be achieved …

AdS3 Holography from the Worldsheet
The AdS/CFT correspondence has played a prominent role in developing our understanding of the holographic nature of quantum gravity, postulating that string theory on Anti-de Sitter (AdS) space is equivalent to a conformal field theory (CFT) on the boundary of AdS. Tractable examples in which both …

Stationary Anti-de Sitter Black Hole Solutions in and out of Equilibrium
… with a negative cosmological constant. The AdS/CFT correspondence has caused an upsurge in studying anti-de Sitter (AdS) space, and under this duality, the study of classical black holes corresponds to studying thermal states of very strongly coupled conformal field theories (CFTs) — an …

The origin of inflation.
The inflationary universe scenario provides an appealing explanation for the riddles of why the observed universe is so flat and isotropic, and it neatly provides a causal mechanism for generating the primordial inhomogeneities which seed the large-scale structure we observe today. However, the …

Entanglement, topology, & renormalization
… in quantum field theory, and its uses for describing underlying structure of states. We begin this journey by focusing on topological quantum field theory in chapters 1 and 2. These chapters are based heavily upon the papers [1] and [2, 3], respectively. In the introduction to chapter 1 we …
