  • Boson dark matter halos with a dominant noncondensed component 
    Abdullin I.G.; Popov V.A. (2021)
    We consider galaxy halos formed by dark matter bosons with mass in the range of about a few tens or hundreds eV. A major part of the particles is in a noncondensed state and described under the Thomas-Fermi approach. Derived ...
  • Massive spin-2 field in arbitrary spacetimes - The detailed derivation 
    Mazuet C.; Volkov M. (2018)
    © 2018 IOP Publishing Ltd and Sissa Medialab. We present the consistent theory of a free massive spin-2 field with 5 degrees of freedom propagating in spacetimes with an arbitrary geometry. We obtain this theory via ...
  • Statefinder analysis of the superfluid Chaplygin gas model 
    Popov V. (2011)
    The statefinder indices are employed to test the superfluid Chaplygin gas (SCG) model describing the dark sector of the universe. The model involves Bose-Einstein condensate (BEC) as dark energy (DE) and an excited state ...
