On Internal Consistency of Holographic Dark Energy Models
R. Horvat
Holographic dark energy (HDE) models, underlain by an effective quantum field theory (QFT) with a manifest UV/IR connection, have become a convincing candidate for the dark energy…
Holographic dark energy: quantum correlations against thermodynamical description
R. Horvat
Classical and quantum entropic properties of holographic dark energy (HDE) are considered in view of the fact that its entropy is far more restrictive than the entropy of a black h…
Constraining interacting dark energy models with flux destabilization
Raul Horvat, Diego Pavon
A destabilization in the transfer energy flux from the vacuum to radiation, for two vacuum decay laws relevant to the dark energy problem, is analyzed using the Landau-Lifshitz flu…
On Cosmological Implications of Gravitational Trace Anomaly
Neven Bilic, Branko Guberina, Raul Horvat +2
We study the infrared effective theory of gravity that stems from the quantum trace anomaly. Quantum fluctuations of the metric induce running of the cosmological constant and the…
Renormalization-group running cosmologies and the generalized second law
R. Horvat
We explore some thermodynamical consequences of accelerated universes driven by a running cosmological constant (CC) from the renormalization group (RG). Application of the general…
