Continuously deformable topological structure

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)

Some time ago, Bazeia and collaborators [D. Bazeia, J. Menezes, R. Menezes, Phys. Rev. Lett. 91 (2003) 241601], introduced a model consisting of a self-interacting scalar field, where the solitonic static configuration presents a kind of static two kinks profile. Here we present a novel model having this not much usual and interesting property. The implications, and possible advantages, of this new exactly solvable non-linear system are addressed. In particular, the consequences for some D-dimensional defects and cosmological scenarios such as the brane worlds are explored. (c) 2009 Elsevier B.V. All rights reserved.
