Five-dimensional Gauss-Bonnet gravity, with one warped extra-dimension,allows classes of solutions where two scalar fields combine either in akink-antikink system or in a trapping bag configuration. While thekink-antikink system can be interpreted as a pair of gravitating domain wallswith opposite topological charges, the trapping bag solution consists of adomain wall supplemented by a non-topological defect. In both classes ofsolutions, for large absolute values of the bulk coordinate (i.e. far from thecore of the defects), the geometry is given by five-dimensional anti-de Sitterspace.Comment: 8 pages, 2 figure
