Critical Temperature in the BCS-BEC Crossover with Spin-Orbit Coupling
Condensed Matter, 2021 We review the study of the superfluid phase transition in a system of fermions whose interaction can be tuned continuously along the crossover from Bardeen–Cooper–Schrieffer (BCS) superconducting phase to a Bose–Einstein condensate (BEC), also in the ...

Fermionic superfluidity with positive scattering length [PDF]
, 2006 Superfluidity in an ultracold Fermi gas is usually associated with either a negative scattering length, or the presence of a two-body bound state. We show that none of these ingredients is necessary to achieve superfluidity.

Superfluid Neutron Matter with a Twist
Universe, 2021 Superfluid neutron matter is a key ingredient in the composition of neutron stars. The physics of the inner crust are largely dependent on those of its S-wave neutron superfluid, which has made its presence known through pulsar glitches and modifications

Magnetohydrodynamics as Superfluidity [PDF]
Physical Review Letters, 2019 We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. This new theory formulates MHD just in terms of conservation equations, including dissipative effects, by introducing appropriate variables such as a magnetic scalar potential, and providing necessary and sufficient conditions to obtain equilibrium ...

Superfluid Boundary Layer [PDF]
Physical Review Letters, 2017 We model the superfluid flow of liquid helium over the rough surface of a wire (used to experimentally generate turbulence) profiled by atomic force microscopy. Numerical simulations of the Gross-Pitaevskii equation reveal that the sharpest features in the surface induce vortex nucleation both intrinsically (due to the raised local fluid velocity) and ...

Transition Metal Dichalcogenides as Strategy for High Temperature Electron-Hole Superfluidity
Condensed Matter, 2020 Condensation of spatially indirect excitons, with the electrons and holes confined in two separate layers, has recently been observed in two different double layer heterostructures.

The 1S0 Pairing Gap in Neutron Matter
Condensed Matter, 2022 We report ab initio calculations of the S wave pairing gap in neutron matter calculated using realistic nuclear Hamiltonians that include two- and three-body interactions.

Experimental signature of quantum turbulence in velocity spectra?
New Journal of Physics, 2021 Velocity measurements in turbulent superfluid helium between co-rotating propellers are reported. The parameters are chosen such that the flow is fully turbulent, and its dissipative scales are partly resolved by the velocity sensors. This allows for the

Rabi Coupled Fermions in the BCS–BEC Crossover
Condensed Matter, 2022 We investigate the three-dimensional BCS–BEC crossover in the presence of a Rabi coupling, which strongly affects several properties of the system, such as the chemical potential, the pairing gap and the superfluid density.
