First-order formalism for dark energy and dust
D. Bazeia, L. Losano, J. J. Rodrigues +1
This work deals with first-order formalism for dark energy and dust in standard cosmology, for models described by real scalar field in the presence of dust in spatially flat space…
Scalar fields, bent branes, and RG flow
D. Bazeia, F. A. Brito, L. Losano
This work deals with braneworld scenarios driven by real scalar fields with standard dynamics. We show how the first-order formalism which exists in the case of four dimensional Mi…
First-order formalism for scalar field in cosmology
D. Bazeia, L. Losano, J. J. Rodrigues
We present a general procedure to solve the equations of motion for cosmological models driven by real scalar fields with first-order differential equations. The method seems to ha…
Deformed defects for scalar fields with polynomial interactions
D. Bazeia, M. A. González León, L. Losano +1
In this paper we use the deformation procedure introduced in former work on deformed defects to investigate several new models for real scalar field. We introduce an interesting de…
Deforming tachyon kinks and tachyon potentials
V. I. Afonso, D. Bazeia, F. A. Brito
In this paper we investigate deformation of tachyon potentials and tachyon kink solutions. We consider the deformation of a DBI type action with gauge and tachyon fields living on…
First-order formalism for bent brane
V. I. Afonso, D. Bazeia, L. Losano
This work deals with braneworld scenarios in the presence of real scalar field with standard dynamics. We show that the first-order formalism, which exists in the case of flat bran…
