Does the second law hold at cosmic scales?
Manuel Gonzalez-Espinoza, Diego Pavón
The second law of thermodynamics is known to hold at small scales also when gravity plays a leading role, as in the case of black holes and self-gravitating radiation spheres. It h…
The Matter Power Spectrum of Dark Energy Models and the Harrison-Zel'dovich Prescription
Iván Durán, Fernando Atrio-Barandela, Diego Pavón
According to the Harrison-Zel'dovich prescription, the amplitude of matter density perturbations at horizon crossing is the same at all scales. Based on this prescription, we show…
Holographic dark energy at the Ricci scale
Iván Durán, Diego Pavón
We consider a holographic cosmological model in which the infrared cutoff is fixed by the Ricci's length and dark matter and dark energy do not evolve separately but interact non-g…
Observational constraints on a holographic, interacting dark energy model
Iván Durán, Diego Pavón, Winfried Zimdahl
We constrain an interacting, holographic dark energy model, first proposed by two of us in [1], with observational data from supernovae, CMB shift, baryon acoustic oscillations, x-…
On the consistency of warm inflation in the presence of viscosity
Sergio del Campo, Ramón Herrera, Diego Pavón +1
This paper studies the stability of warm inflationary solutions when the viscous pressure is taken into account. The latter is a very natural and physically motivated ingredient of…
