Non-Minimally Coupled Chain Inflation at High Scales
Miguel Barroso Varela, Orfeu Bertolami, Katherine Freese +1
Chain inflation offers an alternative to standard slow-roll dynamics, with accelerated expansion proceeding through a sequence of rapid quantum tunneling events between metastable…
On dark sector scalar field theories driven by cosmological -fields
Alex E. Bernardini, Orfeu Bertolami
The interplay of Hoyle-Narlikar (HN) creation field cosmology and scalar field models for the dark sector, including the generalized Chaplygin Gas (GCG), is investigated . Though o…
Toda-like Hamiltonian as a probe for quantized prey-predator dynamics
Alex E. Bernardini, Orfeu Bertolami
Phase-space features of a reduced version of the Toda-like Hamiltonian, , written in a form constrained by the condition $\partial^2 \mathcal{H} / \partial x \p…
Setting up the physical principles of resilience in a model of the Earth System
Orfeu Bertolami, Magnus Nyström
Resilience is a property of social, ecological, social-ecological and biophysical systems. It describes the capacity of a system to cope with, adapt to and innovate in response to…
Cosmological and lunar laser ranging constraints on evolving dark energy in a nonminimally coupled curvature-matter gravity model
Riccardo March, Miguel Barroso Varela, Orfeu Bertolami +3
We analyze a cosmological solution to the field equations of a modified gravity model where curvature and matter are nonminimally coupled. The current Universe's accelerated expans…
Accretion of Generalized Chaplygin Gas onto Cosmologically Coupled Black Holes
Luis F. Reis, Mario C. Baldiotti, Orfeu Bertolami
We study the accretion of cosmic dark fluids, responsible for driving the accelerated expansion of the universe, onto cosmologically coupled black holes. More specifically, we focu…
