Scale-invariant scalar field dark matter through the Higgs portal
Catarina Cosme
We introduce an oscillating scalar field coupled to the Higgs that can account for all dark matter in the Universe. Due to an underlying scale invariance of this model, the dark sc…
A Quantum Field Theory View of Interaction Free Measurements
Filipe Barroso, Orfeu Bertolami
We propose a Quantum Field Theory description of beams on a Mach-Zehnder Interferometer and apply the method to describe Interaction Free Measurements (IFMs), concluding that there…
Cosmological Solutions of the Non-minimally Coupled Weyl Connection Gravity Theories
Rodrigo Baptista, Orfeu Bertolami
We consider a non-minimally coupled curvature-matter gravity model (NMC) with a Weyl connection, a theory referred to as non-minimally coupled Weyl connection gravity (NMCWCG). The…
A Physical Framework for the Earth System in the Anthropocene: Towards an Accountancy System
O. Bertolami, F. Francisco
At a time when humanity has achieved global dominance at a scale that was previously thought impossible, it might also face an existential threat due to the consequences of that ov…
Using numerical methods from nonlocal optics to simulate the dynamics of N-body systems in alternative theories of gravity
Tiago D. Ferreira, Nuno A. Silva, O. Bertolami +2
The generalized Schrödinger-Newton system of equations with both local and nonlocal nonlinearities is widely used to describe light propagating in nonlinear media under the paraxia…
Towards a Physically Motivated Planetary Accounting Framework
M. Barbosa, O. Bertolami, F. Francisco
In this work we present a physically motivated planetary Accounting Framework for the Earth System. We show that the impact of the human activity in terms of the Planetary Boundary…
Ensuring Uninterrupted Power Supply to Lunar Installations Through an Organic Rankine Cycle
F. Francisco, O. Bertolami
We propose using the temperature gradients between the Moon's surface and the soil at a certain depth to power an Organic Rankine Cycle that could supply a permanent installation,…
Constraining a nonminimally coupled curvature-matter gravity model with ocean experiments
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We examine the constraints on the Yukawa regime from the non-minimally coupled curvature-matter gravity theory arising from deep underwater ocean experiments. We consider the geoph…
Nonminimally coupled curvature-matter gravity models and Solar System constraints
Riccardo March, Orfeu Bertolami, Jorge Páramos +1
We discuss constraints to some nonminimally (NMC) coupled curvature-matter models of gravity by means of Solar System experiments. First we discuss a NMC gravity model which consti…
Phase-space continuity equations for quantum decoherence, purity, von Neumann and Rényi entropies
Alex E. Bernardini, Orfeu Bertolami
Phase-space features of the Wigner flow are examined so to provide a set of continuity equations that describe the flux of quantum information in the phase-space. The reported resu…
