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…
Lorentz-violating dimension-five operator contribution to the black body radiation
M. A. Anacleto, F. A. Brito, E. Maciel +4
We investigate the thermodynamics of a photon gas in an effective field theory model that describes Lorentz violations through dimension-five operators and Horava-Lifshitz theory.…
Cosmology from a running vacuum model driven by a scalar field
J. R. L. Santos, P. H. R. S. Moraes
The possibility that the vacuum energy density is, indeed, varying in time, has been investigated lately from the running vacuum models perspective. Motivated by such models,…
New family of potentials with analytical twiston-like solutions
J. R. L. Santos, D. S. S. Borges, I. O. Moreira
In this letter we present a new approach to find analytical twiston models. The effective two-field model was constructed by a non-trivial combination of two one field systems. In…
Harmonic oscillators from displacement operators and thermodynamics
F. A. Brito, F. F. Santos, J. R. L. Santos
In this investigation, the displacement operator is revisited. We established a connection between the Hermitian version of this operator with the well-known Weyl ordering. Besides…
