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 dark energy: a dynamical analysis with complex scalar field
Ricardo C. G. Landim
The dynamical analysis for coupled dark energy with dark matter is presented, where a complex scalar field is taken into account and it is considered in the presence of a barothrop…
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…
