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

Superfluid motion and drag-force cancellation in a fluid of light
Nature Communications, 2018 Superfluidity of light enables movement without friction or, in optical terms, diffraction. Here, Michel et al. report the detection of the transition to superfluidity in the flow of a fluid of light past an obstacle in a bulk nonlinear crystal and ...

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.

Superfluidity in the stochastic limit
Discrete Dynamics in Nature and Society, 2004 We discuss the stochastic limit approach to superfluidity. Starting from the usual Hamiltonian describing the interaction between the Bose condensate and the normal phase, we prove the existence of superfluidity in the stochastic limit and deduce a ...

Classical analogies for the force acting on an impurity in a Bose–Einstein condensate
New Journal of Physics, 2020 We study the hydrodynamic forces acting on a small impurity moving in a two-dimensional Bose–Einstein condensate at non-zero temperature. The condensate is modelled by the damped-Gross Pitaevskii (dGPE) equation and the impurity by a Gaussian repulsive ...

Fortschritte der Physik, 2012 AbstractWe construct holographic superfluid flow solutions in a five‐dimensional theory that arises as a consistent truncation of low energy type IIB string theory. We then study the phase diagram of these systems in terms of the temperature and superfluid velocity.

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.

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
