Superfluid-Insulator Transition unambiguously detected by entanglement in one-dimensional disordered superfluids
(Nature Publishing Group, 2019-10-25)
We use entanglement to track the superfluid-insulator transition (SIT) in disordered fermionic superfluids described by the one-dimensional Hubbard model. Entanglement is found to have remarkable signatures of the SIT ...
Turbulent flow around an oscillating body in superfluid helium: dissipation characteristics of the nonlinear regime
(Springer, 2013-01)
By examining the resonance curves of an oscillator submerged in superfluid liquid helium, it is found that their shape is affected by two distinct dissipation regimes when the amplitude is large enough to generate turbulence ...
Gap solitons in a model of a superfluid fermion gas in optical lattices
(Elsevier B.V., 2009-07-15)
We consider a dynamical model for a Fermi gas in the Bardeen-Cooper-Schrieffer (BCS) superfluid state, trapped in a combination of a ID or 2D optical lattice (OL) and a tight parabolic potential, acting in the transverse ...
Gap solitons in fermion superfluids
(Elsevier B.V., 2009-12-01)
We consider a dynamical model of a superfluid Fermi gas in the Bardeen-Cooper-Schrieffer regime trapped in a periodic optical lattice (OL) potential. The model is based on an equation for complex order parameter phi of the ...

Entanglement in disordered superfluids: The impact of density, interaction and harmonic confinement on the Superconductor-Insulator transition
(Elsevier B.V., 2020-05-01)
We investigate the influence of density, interaction and harmonic confinement on the superfluid to insulator transition (SIT) in disordered fermionic superfluids described by the one-dimensional Hubbard model. We quantify ...
Dual cascade and dissipation mechanisms in helical quantum turbulence
(American Physical Society, 2017-05)
While in classical turbulence helicity depletes nonlinearity and can alter the evolution of turbulent flows, in quantum turbulence its role is not fully understood. We present numerical simulations of the free decay of a ...
Stationary Vortices and Pair Currents in a Trapped Fermion Superfluid
(Springer/Plenum Publishers, 2015-05)
We examine the effects of stationary vortices in superfluid Li atoms at
zero temperature in the frame of the recently developed fluiddynamical scheme, that
includes the pair density and its associated pair current and ...
