Dynamical analysis of logarithmic energy-momentum squared gravity
Giovanni Acquaviva, Nihan Katirci
We perform the dynamical system analysis of a cosmological model in the energy-momentum squared gravity (EMSG) of the form , which is known a…
Dynamical analysis approaches in spatially curved FRW spacetimes
M. Kerachian, G. Acquaviva, G. Lukes-Gerakopoulos
In this article, we summarize two agnostic approaches in the framework of spatially curved Friedmann-Robertson-Walker (FRW) cosmologies discussed in detail in (Kerachian et al., 20…
Dynamics of classes of barotropic fluids in spatially curved FRW spacetimes
Morteza Kerachian, Giovanni Acquaviva, Georgios Lukes-Gerakopoulos
In this article we perform dynamical analysis of a broad class of barotropic fluids in the spatially curved Friedmann-Robertson-Walker (FRW) spacetime background without considerin…
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…
Dynamical analysis of a first order theory of bulk viscosity
Giovanni Acquaviva, Aroonkumar Beesham
We perform a global analysis of curved Friedmann-Robertson-Walker cosmologies in the presence of a viscous fluid. The fluid's bulk viscosity is governed by a first order theory rec…
