Optical Extreme Learning Machines with Atomic Vapors
Nuno A. Silva, Vicente Rocha, Tiago D. Ferreira
Extreme learning machines explore nonlinear random projections to perform computing tasks on high-dimensional output spaces. Since training only occurs at the output layer, the app…
Optical Feedback Loop in Paraxial Fluids of Light: A Gate to new phenomena in analogue physical simulations
Tiago D. Ferreira, Ariel Guerreiro, Nuno A. Silva
Easily accessible through tabletop experiments based on laser propagation inside nonlinear optical media, Paraxial Fluids of Light are emerging as promising platforms for the simul…
Exploring the dynamics of the Kelvin-Helmoltz instability in paraxial fluids of light
Tiago D. Ferreira, Jakub Garwola, Nuno A. Silva
Paraxial fluids of light have recently emerged as promising analogue physical simulators of quantum fluids using laser propagation inside nonlinear optical media. In particular, re…
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…
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…
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…
