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…
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…
