New trends in coherent optical media: models and high-performance simulation from steady-state and beyond

NMA Silva - 2018 - search.proquest.com
Since the very first experiments with light, understanding the interaction between light and
matter posed as a major objective. The optical response of matter to electromagnetic fields …

Slow-light dissipative solitons in an atomic medium assisted by an incoherent pumping field

NA Silva, AL Almeida, A Guerreiro - arXiv preprint arXiv:1810.04638, 2018 - arxiv.org
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 …

Space-time refraction of light in time dependent media: the analogue within the analogue

A Guerreiro, JT Mendonça, JC Costa… - … on Applications of …, 2017 - spiedigitallibrary.org
The problem of electromagnetic wave propagation in time varying media is very old, but in
recent years it has been revisited at a more fundamental level leading to the introduction of …

Pinching optical potentials for spatial nonlinearity management in Bose-Einstein condensates

NA Silva, JC Costa, M Gomes… - … on Applications of …, 2017 - spiedigitallibrary.org
Here we explore the possibility of controlling the inhomogeneities in quasi-1D Bose-Einstein
condensates using a spatial variation of the transverse confinement potential and explore …
