Bridging dimensions: General embedding algorithm and field-theory reconstruction in 5D braneworld models

T Nakas, TD Pappas, Z Stuchlík - Physical Review D, 2024 - APS
We develop a general algorithm that enables the consistent embedding of any four-
dimensional static and spherically symmetric geometry into any five-dimensional single …

Health care expenditures and longevity: is there a Eubie Blake effect?

F Breyer, N Lorenz, T Niebel - The European Journal of Health Economics, 2015 - Springer
It is still an open question whether increasing life expectancy as such causes higher health
care expenditures (HCE) in a population. According to the “red herring” hypothesis, the …

New black-string solutions for an anti–de Sitter brane in scalar-tensor gravity

T Nakas, N Pappas, P Kanti - Physical Review D, 2019 - APS
We consider a five-dimensional theory with a scalar field nonminimally coupled to gravity,
and we look for novel black-string solutions in the bulk. By appropriately choosing the …

Analytic and exponentially localized braneworld Reissner-Nordström-AdS solution: A top-down approach

T Nakas, P Kanti - Physical Review D, 2021 - APS
In this work, we construct a five-dimensional spherically symmetric, charged and
asymptotically anti–de Sitter black hole with its singularity being pointlike and strictly …

On the localization of four-dimensional brane-world black holes

P Kanti, N Pappas, K Zuleta - Classical and Quantum Gravity, 2013 - iopscience.iop.org
In the context of brane-world models, we pursue the question of the existence of five-
dimensional solutions describing regular black holes localized close to the brane …

[HTML][HTML] Localized brane-world black hole analytically connected to an AdS5 boundary

T Nakas, P Kanti - Physics Letters B, 2021 - Elsevier
We construct from first principles the geometry of an analytic, exponentially localized five-
dimensional brane-world black hole. The black-hole singularity lies entirely on the 3-brane …

Null fluid collapse in brane world models

T Harko, MJ Lake - Physical Review D, 2014 - APS
The brane world description of our Universe entails a large extra dimension and a
fundamental scale of gravity that may be lower than the Planck scale by several orders of …

Antigravitating braneworld solutions for a de Sitter brane in scalar-tensor gravity

P Kanti, T Nakas, N Pappas - Physical Review D, 2018 - APS
In the context of a five-dimensional theory with a scalar field nonminimally coupled to gravity,
we look for solutions that describe novel black-string or maximally symmetric solutions in the …

On the localisation of four-dimensional brane-world black holes: II. The general case

P Kanti, N Pappas, T Pappas - Classical and Quantum Gravity, 2015 - iopscience.iop.org
We perform a comprehensive analysis of a number of scalar field theories in an attempt to
find analytically five-dimensional, localised-on-the-brane, black-hole solutions. Extending a …

Five-dimensional gravitational brane-world models: Solutions for black strings and black holes

In the context of this dissertation, we study the emergence of black-string and black-hole
solutions in the framework of five-dimensional braneworld models. The main motivation for …
