Entanglement and exotic superfluidity in spin-imbalanced lattices
(Elsevier B.V., 2017-06-01)
We investigate the properties of entanglement in one-dimensional fermionic lattices at the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superfluid regime. By analyzing occupation probabilities, which are concepts closely related ...
Transition to quantum turbulence in finite-size superfluids
(WILEY-BLACKWELL, 2011)
A novel concept of quantum turbulence in finite size superfluids, such as trapped bosonic atoms, is discussed. We have used an atomic (87)Rb Bose-Einstein condensate (BEC) to study the emergence of this phenomenon. In our ...
Holographic p-wave superfluid with Weyl corrections
(Science Press, 2020-01-01)
In this work, we study the effects of the Weyl corrections on the p-wave superfluid phase transition in terms of an Einstein-Maxwell theory coupled to a complex vector field. In the probe limit, it is observed that the ...
Superfluid 4He: brief notes on collective energy excitations and specific heat.
(Instituto de Física USPSão Paulo, 2013)
These brief notes about some amazing properties of the helium superfluid have been written to graduate and postgraduate students of physics. We have estimated some collective energy excitations (linear vortices, energy ...
Loss of superfluidity in a Bose-Einstein condensate on an optical lattice via a novel classical phase transition
(Elsevier B.V., 2003-03-03)
We predict the loss of superfluidity in a Bose-Einstein condensate (BEC) trapped in a combined optical and axially-symmetric harmonic potentials during a resonant collective excitation initiated by a periodic modulation ...

Vortex pseudomomentum and dissipation in a superfluid vortex lattice
(IOP Publishing, 2008-07)
We propose an alternative approach to the dissipative vortex dynamics occurring in a superfluid vortex lattice at finite temperatures. Focusing upon the pseudomomentum of a vortex and its surrounding quasiparticles, we ...
Universal scaling in a trapped Fermi super-fluid in the BCS-unitarity crossover
(Wiley-v C H Verlag Gmbh, 2009-12-01)
Using numerical simulation based-on a density-functional equation for a trapped Fermi-super-fluid valid along the BCS-unitarity crossover, we establish robust scaling over many orders of magnitude in the observables of the ...
