Wave function of the radion in a brane world
Christos Charmousis, Ruth Gregory, Valery A. Rubakov
We calculate the linearized metric perturbation corresponding to a massless four-dimensional scalar field, the radion, in a five-dimensional two-brane model of Randall and Sundrum.…
Nonsingular global string compactifications
Ruth Gregory
We consider an exotic `compactification' of spacetime in which there are two infinite extra dimensions, using a global string instead of a domain wall. By having a negative cosmolo…
Vortices and black holes in dilatonic gravity
Caroline Santos, Ruth Gregory
We study analytically black holes pierced by a thin vortex in dilatonic gravity for an arbitrary coupling of the vortex to the dilaton in an arbitrary frame. We show that the horiz…
Thick self-gravitating plane-symmetric domain walls
Filipe Bonjour, Christos Charmousis, Ruth Gregory
We investigate a self-gravitating thick domain wall for a potential. The system of scalar and Einstein equations admits two types of non-trivial solutions: domain wall solut…
Thick domain wall universes
Filipe Bonjour, Christos Charmousis, Ruth Gregory
We investigate the spacetime of a thick gravitating domain wall for a general potential . Using general analytical arguments we show that all nontrivial solutions fall into t…
