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…
