A general method for transforming non-physical configurations in BPS states
J. R. L. Santos, A. de Souza Dutra, O. C. Winter +1
In this work, we apply the so-called BPS method in order to obtain topological defects for a complex scalar field Lagrangian introduced by Trullinger and Subbaswamy. The BPS approa…
D-Oscillons in the Standard Model-Extension
R. A. C. Correa, Roldao da Rocha, A. de Souza Dutra
In this work we investigate the consequences of the Lorentz symmetry violation on extremely long-living, time-dependent, and spatially localized field configurations, named oscillo…
Fluctuating solutions for the evolution of domain walls
A. de Souza Dutra, R. A. C. Correa
A class of oscillating Lorentz covariant configurations for the evolution of the domain walls in diverse dimensions are analytically obtained. It is shown that the oscillating solu…
Degenerate and critical domain walls and accelerating universes driven by bulk particles
A. de Souza Dutra, A. C. Amaro de Faria, M. Hott
We consider a scenario where our universe is taken as a three-dimensional domain wall embedded in a five-dimensional Minkowski space-time, as originally proposed by Brito and colla…
Degenerate and critical Bloch branes
A. de Souza Dutra, A. C. Amaro de Faria, M. Hott
In the last few years a number of works reported the appearance of thick branes with internal structure, induced by the parameter which controls the interaction between two scalar…
Multiflavor Soldering
D. Dalmazi, A. de Souza Dutra
In two dimensions the simple addition of two chiral bosons of opposite chiralities does not lead to a full massless scalar field. Similarly, in three dimensions the addition of two…
