Gauge field and brane-localized kinetic terms on the chiral square
Ricardo G. Landim
Extra dimensions have been used as attempts to explain several phenomena in particle physics. In this paper we investigate the role of brane-localized kinetic terms (BLKT) on thin…
Dynamical analysis for a vector-like dark energy
Ricardo C. G. Landim
In this paper we perform a dynamical analysis for a vector field as a candidate for the dark energy, in the presence of a barothropic fluid. The vector is one component of the so-c…
Cosmological tracking solution and the Super-Higgs mechanism
Ricardo C. G. Landim
In this paper we argue that minimal supergravity with flat Kähler metric and a power-law superpotential can relate the Super-Higgs mechanism for the local spontaneous supersymmetry…
Holographic dark energy from minimal supergravity
Ricardo C. G. Landim
We embed models of holographic dark energy coupled to dark matter in minimal supergravity plus matter, with one chiral superfield. We analyze two cases. The first one has the Hubbl…
Coupled tachyonic dark energy: a dynamical analysis
Ricardo C. G. Landim
In this paper we present a dynamical analysis for a coupled tachyonic dark energy with dark matter. The tachyonic field is considered in the presence of barothropic fluids (mat…
Inflation and Dark Energy from a Scalar Field in Supergravity
Ricardo C. G. Landim
In this paper we present a model for accelerated expansion of the universe, both during inflation and the present stage of the expansion, from four dimensional supe…
