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…

Ruth Gregory
We examine a Nambu-Goto string trajectory in the neighbourhood of a cusp and determine the extrinsic curvature invariants. These are demonstrated to be finite, in contradiction wit…
