Plasmon dispersion and Landau damping in the nonlinear quantum regime
F. Haas, J. T. Mendonça, H. Terças
We study the dispersion properties of electron plasma waves, or plasmons, which can be excited in quantum plasmas in the nonlinear regime. In order to describe nonlinear electron r…
Towards a kinetic theory of a dark soliton gas in one-dimensional superfluids
C. Pereira, J. D. Rodrigues, J. T. Mendonça +1
Soliton hydrodynamics is an appealing tool to describe strong turbulence in low-dimensional systems. Strong turbulence in quasi-one dimensional spuerfluids, such as Bose-Einstein c…
Violation of the PT-symmetry and structure formation in the dark matter-gravitational wave interaction
Catarina Bastos, Hugo Terças
In flat spacetime, quantum fluctuations in dark matter, as described as a Bose-Einstein condensate, are stable and display a relativistic Bogoliubov dispersion relation. In the wea…
Sympathetic laser-cooling of graphene with Casimir-Polder forces
Sofia Ribeiro, Hugo Terças
We propose a scheme to actively cool the fundamental flexural (out-of-plane) mode of a graphene sheet via vacuum forces. Our setup consists in a cold atom cloud placed close to a g…
Optical amplifier based on guided polaritons in GaN and ZnO
D. D. Solnyshkov, H. Terças, G. Malpuech
We propose a scheme of an optical amplifier based on GaN and ZnO waveguides operating in the regime of strong coupling between photonic modes and excitonic resonances. Amplificatio…
Phonon-polaritons in Bose-Einstein condensates induced by Casimir-Polder interaction with graphene
H. Terças, S. Ribeiro, J. T. Mendonça
We consider the mechanical coupling between a two-dimensional Bose-Einstein condensate with a graphene sheet via the vacuum fluctuations of the electromagnetic field which are at t…
