1. Relativistic dispersion relation and putative metric structure in noncommutative phase-space / Leal, P. ; Bertolami, O.
The deformation of the relativistic dispersion relation caused by noncommutative (NC) Quantum Mechanics (QM) is studied using the extended phase-space formalism. [...]

2. Inflation with Planck data: A survey of some exotic inflationary models / Gomes, Cláudio ; Bertolami, Orfeu ; Rosa, João G.
We examine some inflationary models based on modifications of gravity in the light of Planck 2015 data, such as the generalized Chaplygin inspired inflation, models based in N=1 supergravity and braneworld scenarios. [...]

3. Scale-invariant scalar field dark matter through the Higgs portal / Cosme, Catarina ; Rosa, João ; Bertolami, O.
We discuss the dynamics and phenomenology of an oscillating scalar field coupled to the Higgs boson that accounts for the dark matter in the Universe. [...]

4. Scalar field dark matter with spontaneous symmetry breaking and the 3.5 keV line / Cosme, Catarina ; Rosa, João G. ; Bertolami, O.
We show that the present dark matter abundance can be accounted for by an oscillating scalar field that acquires both mass and a non-zero expectation value from interactions with the Higgs field. [...]

5. Gravitational waves in theories with a non-minimal curvature-matter coupling / Bertolami, Orfeu ; Gomes, Cláudio ; Lobo, Francisco S. N.
Gravitational waves in the presence of a non-minimal curvature-matter coupling are analysed, both in the Newman–Penrose and perturbation theory formalisms. [...]
