  • Bose condensation in (random) traps 
    Jaeck, Th.; Pulé, J.V.; Zagrebnov, V.A. (Condensed Matter Physics, 2009)
    We study a non-interacting (perfect) Bose-gas in random external potentials (traps). It is shown that a generalized Bose-Einstein condensation in the random eigenstates manifests if and only if the same occurs in the ...
  • Generalized condensation and the Bogoliubov theory of superfluidity 
    Zagrebnov, V.A. (Condensed Matter Physics, 2000)
    In this paper we scrutinize the Bogoliubov theory of superfluidity on the level of the first Bogoliubov ansatz. This ansatz preconizes the Bogoliubov truncated Hamiltonian as a starting point of this theory. Since this ...
  • The second critical density and anisotropic generalised condensation 
    Beau, M.; Zagrebnov, V.A. (Condensed Matter Physics, 2010)
    In this letter we discuss the relevance of the 3D Perfect Bose gas (PBG) condensation in extremely elongated vessels for the study of anisotropic condensate coherence and the "quasi-condensate". To this end we analyze the ...
