Emergent Times in Holographic Duality
… AdS black hole is described by two copies of the boundary CFT in the thermal eld double state. In this thesis we provide explicit constructions in the boundary theory of infalling time evolutions which can take bulk observers behind the horizon. The constructions also help to illuminate the …

Aspects of finite temperature field theories in Ads/CFT
… 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 correlation functions of gauge invariant single-trace operators in the low temperature phase are related to those at zero temperature by …

Entanglement entropy, the Ryu-Takayanagi prescription, and conformal maps
… for entanglement entropy in a holographic theory. We begin by constructing entanglement entropy in finite-dimensional quantum systems, and defining the boundary at infinity of a bulk spacetime. This is sufficient for a naïve application of the Ryu-Takayanagi prescription to some simple …

Food Consumption Similarities and Differences for Two Types of Jamaican Households
… combining ideas from Bourdieu, Barth’s ethnic boundary theory, Yosso’s cultural capital and Strauss’s negotiated order. There was a significant relationship between the two household types and ethnic food purchases, and frequency of consuming Jamaican dishes at home; and between the importance …

Gauge/Gravity Duality: Recovering the Bulk from the Boundary using AdS/CFT
… information of physical quantities in the dual boundary CFT. In particular, we use the existence of bulk-cone singularities (relating the location of operator insertion points of singular boundary correlation functions to the endpoints of boundary-to boundary null geodesics in the bulk …

Relativistic and non-relativistic holography
… of the most interesting developments in String theory in the past few years. In this thesis, we discuss various aspects of the correspondence at the phenomenological and conceptual levels. At the phenomenological level, holographic duals of strong coupling QCD-like boundary theories is …

Teleworker Well-Being in COVID-19 as a Function of Change in the Work/Home Boundary: A Multilevel Response Surface Approach
… explored how a change in the work/home boundary stemming from a mandatory switch to full-time telework influenced employee well-being. Organizational scholars have called for more investigations into how crisis events impact employees, and the COVID-19 pandemic presented an opportunity …

Work-life interaction of Setswana speaking police officers : a phenomenological study
… and conflicting aspects. Recent developments in boundary theory highlighted the fact that integrating, or rather interaction means bordering between the two domains of work and personal life is permeable. The main objective of this study was to investigate work-personal life interaction (WPLI) …

Cauchy Slice Holography and the Semiclassical Approximation
… of a Euclidean CFT, we define a holographic theory that lives on Cauchy slices of the Lorentzian bulk. (More generally, for an arbitrary Hamiltonian constraint equation that closes, we show how to obtain it by an irrelevant deformation from a CFT with suitable anomalies.) The partition …

Stationary Anti-de Sitter Black Hole Solutions in and out of Equilibrium
… the most fundamental objects in any physical theory. In this thesis we numerically obtain a number of stationary black hole solutions to the Einstein-Maxwell equations with a negative cosmological constant. The AdS/CFT correspondence has caused an upsurge in studying anti-de Sitter (AdS) …

Holography and strongly correlated systems
… thesis we apply techniques arising from string theory - gauge-gravity/duality, or holography - to problems associated with strongly coupled quantum field theories under extreme conditions such as finite temperature or density. We first study a strongly coupled field theory at finite temperature. …

The experiences of academics working remotely during the Covid-19 Pandemic in South Africa
Academics needed to urgently move to remote working from their homes due to the COVID-19 pandemic, and develop new ways of teaching and research, to ensure the continuity of the academic project. The purpose of the study was to explore this experience during this uncertain time. Using an …

Topological insulators and semimetals in the presence of interactions
… is to examine the quantum anomalies in the boundary theory, which indicates the presence of the non-trivial topology in the higher dimensional bulk. This approach is based on the fact that if the edge theory has a non-trivial response to certain transformations, then the edge theory cannot …
