Pressureless stationary solutions in a Newton-Yukawa gravity model
T. D. Ferreira, J. Novo, N. A. Silva +2
Non-minimally coupled curvature-matter gravity models are an interesting alternative to the Theory of General Relativity and to address the dark energy and dark matter cosmological…
Hight temperature generation of entangled light in parametrically excited micro and nano-ring ressonators for integrated optics
D. M. N. Magano, P. A. M. Macedo, A. Guerreiro
We propose a physical scheme to generate entangled light at high temperatures through the excitation of vacuum fluctuations of the electromagnetic field using periodic modulations…
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…
New insight into EM radiation from spinning dust and its influence on the Cosmic Microwave Background
Ariel Guerreiro, José Tito Mendonça, Robert Bingham
Dust is ubiquitous in the Universe and its influence on the observed Electromagnetic (EM) radiation needs to be correctly addressed. In recent years it became clear that scattering…
Slow-light dissipative solitons in an atomic medium assisted by an incoherent pumping field
Nuno A. Silva, André L. Almeida, A. Guerreiro
This work models the propagation of an optical pulse in a 4-level atomic system in the electromagnetic induced transparency regime. By demonstrating that linear and nonlinear optic…
The role of local field modes in calculating the effective optical properties of metamaterials
Anderson O. Silva, Ivo T. Leite, José M. Teixeira +3
This letter discusses the importance of the nature of local fields inside a unit cell of optical metamaterials in developing a valid effective medium theory. In particular, we appl…
