Stability of a modified Jordan-Brans-Dicke theory in the dilatonic frame
Genly Leon, Andronikos Paliathanasis, Luisberis Velazquez Abad
We investigate the Jordan-Brans-Dicke action in the cosmological scenario of FLRW spacetime with zero spatially curvature and with an extra scalar field minimally coupled to gravit…
Exact Solutions in Chiral Cosmology
Andronikos Paliathanasis, Genly Leon, Supriya Pan
In multi-scalar field cosmologies new dynamical degrees of freedom are introduced which can explain the observational phenomena. Unlike the usual scalar field theory where a single…
The past and future dynamics of quintom dark energy models
Genly Leon, Andronikos Paliathanasis, Jorge Luis Morales-Martínez
We study the phase space of the quintom cosmologies for a class of exponential potentials. We combine normal forms expansions and the center manifold theory in order to describe th…
Dynamical systems analysis of the cubic galileon beyond the exponential potential and the cosmological analogue of the vDVZ discontinuity
Roberto De Arcia, Tame Gonzalez, Francisco Antonio Horta-Rangel +3
In this paper we generalize the dynamical systems analysis of the cubic galileon model previously investigated in \cite{rtgui} by including self-interaction potentials beyond the e…
