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…
Holographic dark energy in Brans-Dicke theory
Narayan Banerjee, Diego Pavon
In this Letter it is shown that when the holographic dark energy is combined with the Brans-Dicke field equations the transition from decelerated to accelerated expansion of the Un…
The Generalized Second Law in Dark Energy Dominated Universes
German Izquierdo, Diego Pavon
The generalized second law of gravitational thermodynamics is examined in scenarios where the dark energy dominates the cosmic expansion. For quintessence and phantom fields this l…
Quintessence inhomogeneous cosmology
Luis P. Chimento, Alejandro S. Jakubi, Diego Pavon
The Einstein-Klein-Gordon field equations are solved in a inhomogeneous shear-free universe containing a material fluid, a self-interacting scalar field, a variable cosmological te…
The Case for Hyperbolic Theories of Dissipation in Relativistic Fluids
Angelo M. Anile, Diego Pavon, Vittorio Romano
In this paper we highlight the fact that the physical content of hyperbolic theories of relativistic dissipative fluids is, in general, much broader than that of the parabolic ones…
