Superfluidity from correlations in driven boson systems
New Journal of Physics, 2023 We investigate theoretically the superfluidity of a one-dimensional boson system whose hopping energy is periodically modulated with a zero time average, which results in the suppression of first-order single-particle hopping processes.

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 ...

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.

Journal of High Energy Physics, 2019 Abstract We present a complete classification of symmetric superfluids, namely shift-symmetric and Poincaré invariant scalar field theories that have an enlarged set of classically conserved currents at leading order in derivatives.

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 ...

Physical Review Research, 2020 We theoretically investigate how the presence of a reservoir of incoherent excitations affects the superfluidity properties of resonantly driven polariton fluids.

Observation of pseudogap behavior in a strongly interacting Fermi gas [PDF]
, 2010 Ultracold atomic Fermi gases present an opportunity to study strongly interacting Fermi systems in a controlled and uncomplicated setting. The ability to tune attractive interactions has led to the discovery of superfluidity in these systems with an ...

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 ...

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 ...
