Unified dynamical system formulations for gravity with applications to nonminimal derivative coupling and -Higgs inflation

Saikat Chakraborty, Sergio E. Jorás, Alberto Saa

Two different dynamical system formulations are presented that can be implemented to analyze a rather large class of modified gravity theories within the generic family.…

Composite Dissipation in Warm Inflation: Implications for the Primordial Power Spectrum

Ayush Sahu, Richa Arya, Sergio E. Jorás +1

Warm inflation is a well-motivated and generalized framework of inflation, describing a coupled inflaton-radiation bath. In this work, we investigate a warm inflation model with a…

Parametric Resonance in the Einstein frame: the Jordan-frame Doppelgänger

Karim H. Seleim, Richa Arya, Sergio E. Jorás

Modified theories of gravity have been investigated for quite a long time in the literature as a possible explanation for the inflationary period of the universe. The corres…

Compact stars in scalar-tensor theories with a single-well potential and the corresponding theory

Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +2

The macroscopic properties of compact stars in modified gravity theories can be significantly different from the general relativistic (GR) predictions. Within the gravitational con…

Thermodynamics of Gravity: The Double Well Potential Case

C. D. Peralta, S. E. Jorás

In this work we further extend the analysis of theories of gravity in the metric formalism under the approach of a Thermodynamics analogy, proposed in arXiv:1911.04830v3. He…
