Restricted baby Skyrme-Maxwell theory in a magnetic medium: BPS configurations and some properties
J. Andrade, R. Casana, E. da Hora +1
We study the existence of BPS configurations in a restricted baby Skyrme-Maxwell enlarged via the inclusion of a nontrivial magnetic permeability. In order to attain such a goal, w…
Vacuum state perturbed by an oscillon: composite configurations in model
Fabiano C. Simas, E. da Hora
We examine the evolution of a vacuum configuration when perturbed by an oscillon. We consider the scenario with a single scalar field only. For highly excited oscillons, we f…
