Classes of non-minimally coupled scalar fields in spatially curved FRW spacetimes
Morteza Kerachian, Giovanni Acquaviva, Georgios Lukes-Gerakopoulos
In this work we perform a dynamical analysis of a broad class of non-minimally coupled real scalar fields in the Friedmann-Robertson-Walker (FRW) spacetime framework. The first par…

Probing Dark Energy through Perfect Fluid Thermodynamics
Georgios Lukes-Gerakopoulos, Giovanni Acquaviva, Charalampos Markakis
We demonstrate that the thermodynamics of a perfect fluid describing baryonic matter can, in certain limits, lead to an equation of state similar to that of dark energy. We keep th…
