An effective model for inflation from geometrothermodynamics: a detailed analysis of thermodynamics and cosmological perturbations
Christine Gruber, Hernando Quevedo
Inflationary models usually assume the existence of scalar fields or other exotic gravitational sources. We investigate an alternative approach in which the entire Universe is cons…
The zeroth law in quasi-homogeneous thermodynamics and black holes
Alessandro Bravetti, Christine Gruber, Cesar S. Lopez-Monsalvo +1
Motivated by black holes thermodynamics, we consider the zeroth law of thermodynamics for systems whose entropy is a quasi-homogeneous function of the extensive variables. We show…
Geometrothermodynamic model for the evolution of the Universe
Christine Gruber, Hernando Quevedo
Using the formalism of geometrothermodynamics to derive a fundamental thermodynamic equation, we construct a cosmological model in the framework of relativistic cosmology. In a fir…
Geometric approaches to the thermodynamics of black holes
Christine Gruber, Orlando Luongo, Hernando Quevedo
In this summary, we present the main topics of the talks presented in the parallel session "Black holes - 5" of the 14th Marcel Grossmann Meeting held in Rome, Italy in July 2015.…
Black hole thermodynamics in finite time
Christine Gruber
Finite-time thermodynamics provides the means to revisit ideal thermodynamic equilibrium processes in the light of reality and investigate the energetic "price of haste", i.e. the…
Thermodynamic optimization of a Penrose process: an engineers' approach to black hole thermodynamics
Alessandro Bravetti, Christine Gruber, Cesar S. Lopez-Monsalvo
In this work we present a new view on the thermodynamics of black holes introducing effects of irreversibility by employing thermodynamic optimization and finite-time thermodynamic…
