Modelling of vorticity, sound and their interaction in two-dimensional superfluids
Vorticity in two-dimensional superfluids is subject to intense research efforts due to its role in quantum turbulence, dissipation and the BKT phase transition.

Multiple period states of the superfluid Fermi gas in an optical lattice
We study multiple period states of a two-component unpolarized superfluid Fermi gas in an optical lattice along the Bardeen–Cooper–Schrieffer (BCS) to Bose–Einstein condensate (BEC) crossover.

Feynman, a superfluidez e a supercondutividade
Resumo É apresentada uma exposição breve e, na medida do possível, leve, das ideias em torno do entendimento da superfluidez e sua relação com a supercondutividade, com destaque ao papel de Richard Feynman.

Localization of weakly interacting Bose gas in quasiperiodic potential
We study the localization properties of weakly interacting Bose gas in a quasiperiodic potential. The Hamiltonian of the non-interacting system reduces to the well known ‘Aubry–André model’, which shows the localization transition at a critical strength ...

The geometric contribution to superfluid density has been found to be of great importance in the inner crust of neutron stars. In this work we clarify how this contribution arises in the context of a band theory for neutrons.

Einstein–Bose condensation of Onsager vortices
We have studied statistical mechanics of a gas of vortices in two dimensions. We introduce a new observable—a condensate fraction of Onsager vortices—to quantify the emergence of the vortex condensate.

Dark matter superfluidity and galactic dynamics
We propose a unified framework that reconciles the stunning success of MOND on galactic scales with the triumph of the ΛCDM model on cosmological scales. This is achieved through the physics of superfluidity.

Impact of pairing on thermodynamical properties of stellar matter
Superfluidity in the crust is a key ingredient for the cooling properties of proto-neutron stars. Investigations on crust superfluidity carried out so far typically assumed that the cluster component was given by a single representative nucleus and did ...

Density Collective Modes of Exciton Superfluidity in Bilayer Systems
We propose a new way to establish the existence of a superfluid phase in an exciton bilayer system by exploiting the properties of its collective modes. We focus on the density collective modes and treat them within Random Phase Approximation.
