Starobinsky-like inflation and running vacuum in the context of Supergravity
TL;DR: In this paper, the primeval inflationary phase of the early universe was described within a quantum field theoretical framework that can be viewed as the effective action of vacuum decay in the early times.
Phase space analysis of the accelerating multifluid Universe
TL;DR: In this paper, the phase space of a Friedmann-Robertson-Walker universe with various cosmological fluids that may or may not interact is studied, and the physical significance of the resulting fixed points is analyzed.

Observational constraints on an interacting dark energy model
TL;DR: In this paper, the authors used observations of cosmic microwave background (CMB) anisotropies, supernova luminosities and the baryon acoustic oscillation signal in the galaxy distribution to constrain the cosmological parameters in a simple interacting dark energy model with a time-varying equation of state.

Restoring holographic dark energy in brane cosmology
TL;DR: In this article, a generalized version of holographic dark energy is presented, arguing that it must be considered in the maximally subspace of a cosmological model and that a finite bulk can lead to radically different results.

Thermodynamics of cosmological horizons in f (t) gravity
TL;DR: In this article, the authors explore the thermodynamics of the apparent horizon in f(T) gravity with both equilibrium and non-equilibrium descriptions, and show that the second law of thermodynamics can be satisfied for the universe with the same temperature outside and inside the visible horizon.

Holographic dark energy in braneworld models with a Gauss–Bonnet term in the bulk. Interacting behavior and the w=−1 crossing
TL;DR: In this paper, the Friedmann equation on the physical brane is extracted and a ρ − ρ Λ coupling arises naturally by the full 5D dynamics, showing that the effective 4D holographic dark energy behaves as quintom, that is it crosses the phantom divide w = − 1 during the evolution.

Cosmological Solutions of $f(T)$ Gravity
TL;DR: In the cosmological scenario in $f(T)$ gravity, this paper derived exact solutions for an isotropic and homogeneous universe containing a dust fluid and radiation and for an empty anisotropic Bianchi I universe.
