Conical singularities regularized in warped six-dimensional flux compactification and their induced brane cosmology
Vassilios Zamarias
We discuss the regularization of codimension-2 singularities in warped six-dimensional Einstein-Maxwell axisymmetric models by replacing them by codimension-1 branes of a ring form…
Black Holes on Thin 3-branes of Codimension-2 and their Extension into the Bulk
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We discuss black hole solutions in six-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a thin 3-brane of codimension-2. We show that these b…
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…
Geometrical Tachyon Inflation in the Presence of a Bulk Tachyon Field
Vassilios Zamarias
We present the study of the dynamics of the geometrical tachyon field on an unstable D3-brane in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theo…
Geometrical Tachyon Dynamics in the Background of a Bulk Tachyon Field
Eleftherios Papantonopoulos, Ioanna Pappa, Vassilios Zamarias
We study the dynamics of a D3-brane moving in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theory. We show that the dynamics on the probe D3-brane…
