Vortex shedding frequency of a moving obstacle in a Bose–Einstein condensate
New Journal of Physics, 2022 We experimentally investigate the periodic vortex shedding dynamics in a highly oblate Bose–Einstein condensate using a moving penetrable Gaussian obstacle.

A Superfluid Perspective on Neutron Star Dynamics
Universe, 2021 As mature neutron stars are cold (on the relevant temperature scale), one has to carefully consider the state of matter in their interior. The outer kilometre or so is expected to freeze to form an elastic crust of increasingly neutron-rich nuclei ...

Superfluid within superfluid [PDF]
Nature, 1976 At last, somebody has gone out on a limb and named an encouraging number for the temperature of the anticipated superfluid transition among the 3He atoms of a liquid 3He-4He solution. According to Patton and Zaringhalam of the Massachusetts Institute of Technology, writing in a recent issue of Physics Leiters (55A, 95; 1975), the transition is likely ...

Superconducting Phases in Neutron Star Cores
Universe, 2022 Using a phenomenological Ginzburg–Landau model that includes entrainment, we identify the possible ground states for the neutron and proton condensates in the core of a neutron star, as a function of magnetic field strength.

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 ...

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 ...

Superfluid behavior of a Bose–Einstein condensate in a random potential
New Journal of Physics, 2015 We investigate the relation between Bose–Einstein condensation (BEC) and superfluidity in the ground state of a one-dimensional model of interacting bosons in a strong random potential.

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.
