Phase-space origin of superfluid stability in ring Bose-Einstein condensates
M. O. C. Pires
We present a kinetic description of superfluid currents in ring-shaped Bose-Einstein condensates based on the Wigner phase-space formalism. Starting from the Gross-Pitaevskii equat…
Comparison between the numerical solutions and the Thomas-Fermi approximation for atomic-molecular Bose-Einstein condensates
Leonardo S. F. Santos, Marcelo O. C. Pires, Davi Giugno
We study the stationary solution of an atomic Bose-Einstein condensate coupled coherently to a molecular condensate with both repulsive and attractive interspecies interactions con…
Discussion on the energy content of the galactic dark matter Bose-Einstein condensate halo in the Thomas-Fermi approximation
J. C. C. de Souza, M. O. C. Pires
We show that the galactic dark matter halo, considered composed of an axionlike particles Bose-Einstein condensate \cite{pir12} trapped by a self-graviting potential \cite{boh07},…
Domain Wall Model in the Galactic Bose-Einstein Condensate Halo
J. C. C. de Souza, M. O. C. Pires
We assume that the galactical dark matter halo, considered composed of an axionlike particles Bose-Einstein condensate \cite{pir12}, can present topological defects, namely domain…
Generalized Wick's theorem at finite temperature for a quadratic Hamiltonian
M. O. C. Pires
In Gaudin (1960), Michel Gaudin showed the Wick's theorem at finite temperature using a diagonal Hamiltonian. We extend the Gaudin's prove for a statistical density operator which…
Galactic cold dark matter as a Bose-Einstein condensate of WISPs
M. O. C. Pires, J. C. C. de Souza
We propose here the dark matter content of galaxies as a cold bosonic fluid composed of Weakly Interacting Slim Particles (WISPs), represented by spin-0 axion-like particles and sp…
