Generation and decay of Higgs mode in a strongly interacting Fermi gas

Autor: Andrea Barresi, Antoine Boulet, Gabriel Wlazłowski, Piotr Magierski

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-11 (2023)

Abstract We investigate the life cycle of the large amplitude Higgs mode in strongly interacting superfluid Fermi gas. Through numerical simulations with time-dependent density functional theory and the technique of the interaction quench, we verify

Dissipative Dynamics of Quantum Vortices in Fermionic Superfluid

Autor: Antoine Boulet, Andrea Barresi, Piotr Magierski, Gabriel Wlazłowski

Publikováno v: Physical Review Letters. 130

In a recent article, Kwon et al. [Nature (London) {\bf 600}, 64 (2021)] revealed nonuniversal dissipative dynamics of quantum vortices in a fermionic superfluid. The enhancement of the dissipative process is pronounced for the Bardeen-Cooper-Schrieff

Local energy density functional for superfluid Fermi gases from effective field theory

Autor: Antoine Boulet, Piotr Magierski, Gabriel Wlazłowski

Over the past two decades, many studies in the Density Functional Theory context revealed new aspects and properties of strongly correlated superfluid quantum systems in numerous configurations that can be simulated in experiments. This was made poss

The thermodynamical ground-state properties and static response in both cold atoms at or close to unitarity and neutron matter are determined using a recently proposed Density Functional Theory (DFT) based on the s-wave scattering length $a_s$, effec

Approximate self-energy for Fermi systems with large s-wave scattering length: a step towards density functional theory

Autor: Denis Lacroix, Antoine Boulet

Journal of Physics G: Nuclear and Particle Physics

In the present work, we start from a minimal Hamiltonian for Fermi systems where the s-wave scattering is the only low energy constant at play. Many-Body Perturbative approach that is usually valid at rather low density is first discussed. We then us

We further progress along the line of Ref. [D. Lacroix, Phys. Rev. A 94, 043614 (2016)] where a functional for Fermi systems with anomalously large $s$-wave scattering length ${a}_{s}$ was proposed that has no free parameters. The functional is desig

Turondin releva l'épée émoussée qu'il venait d'abaisser. Son bras se fatiguait, mais il devait se tenir prêt à combattre; Amalo le lui ordonnait. Exténué, il para l'attaque de son rival qui s'épuisait tout autant que lui. Il recula légèrem

Princes de cœur

Autor: Antoine Boulet

Le Soleil était soudain vif et l'air plutôt frais, et le matin peu entamé. Toutefois, personne ne dormait plus au sein de Cat-l-eau. Turondin, fatigué et désireux d'admirer le présent qui venait de lui être remis, regardait les Minaigles dispa
