String-Like BTZ on Codimension-2 Braneworlds in the Thin Brane Limit
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We consider five-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a 2-brane of codimension-2. We show that this system admits BTZ black holes…
Observational constrains on the DGP brane-world model with a Gauss-Bonnet term in the bulk
Jian-Hua He, Bin Wang, Eleftherios Papantonopoulos
Using the data coming from the new 182 Gold type Ia supernova samples, the baryon acoustic oscillation measurement from the Sloan Digital Sky Survey and the H(z) data, we have perf…
Induced cosmology on a regularized brane in six-dimensional flux compactification
Eleftherios Papantonopoulos, Antonios Papazoglou, Vassilios Zamarias
We consider a six-dimensional Einstein-Maxwell system compactified in an axisymmetric two-dimensional space with one capped regularized conical brane of codimension one. We study t…
UV stable, Lorentz-violating dark energy with transient phantom era
Maxim Libanov, Eleftherios Papantonopoulos, Valery Rubakov +2
Phantom fields with negative kinetic energy are often plagued by the vacuum quantum instability in the ultraviolet region. We present a Lorentz-violating dark energy model free fro…
