Nonminimally coupled Weyl gravity

Cláudio Gomes, Orfeu Bertolami

Weyl gravity in the presence of a non-minimal matter-curvature coupling is presented. Some properties arising from the non-metricity give rise to a second order theory whose vacuum…

A phase-space description of the Earth System in the Anthropocene

O. Bertolami, F. Francisco

Based on a dynamic systems approach to the Landau-Ginzburg model, a phase space description of the Earth System (ES) in the transition to the Anthropocene is presented. It is shown…

Can dark matter drive electroweak symmetry breaking?

Catarina Cosme, João G. Rosa, Orfeu Bertolami

We consider the possibility of an oscillating scalar field accounting for dark matter and dynamically controlling the spontaneous breaking of the electroweak symmetry through a Hig…

Cosmology with SKA

Orfeu Bertolami, Cláudio Gomes

We review some of the major contributions that the Square Kilometer Array (SKA) will provide for Cosmology. We discuss the SKA measurements of the equation of state parameter for d…

Inflation with Planck: a survey of some "exotic" inflationary models

Cláudio Gomes, Orfeu Bertolami, João G. Rosa

We examine some inflationary models based on modifications of gravity in the light of Planck 2015 data, such as the generalised Chaplygin inspired inflation, models based in

A physical framework for the Earth System, the Anthropocene Equation and the Great Acceleration

O. Bertolami, F. Francisco

It is proposed, based on the Landau-Ginzburg Theory of phase transitions, that the transition of the Earth System from the stable conditions of the Holocene to the human driven con…
