DESCRIPTION:Speakers: Maxim Dvornikov (Institute of Terrestrial Magnetism\
 , Ionosphere and Radiowave Propagation (IZMIRAN))\nThe formation of a neut
 rino cluster due to an attractive interaction with a hypothetical light sc
 alar boson is studied. The density distribution of the neutrino gas within
  the cluster is obtained for various system parameters. It is shown that\,
  in addition to forming a cluster in space\, the neutrino gas within it ca
 n form a superfluid condensate. An energy gap equation is derived for such
  a system\, and the phase transition temperature and coherence length with
 in the cluster are found. Constraints on the parameters of the interaction
  leading to neutrino superfluidity are derived. It is found that the super
 fluid condensate within the cluster consists of relic neutrinos. A neutrin
 o cluster cooling channel based on the Cherenkov emission of neutrinos in 
 matter is studied if the cluster forms in the early universe. A temperatur
 e range is obtained for which Cherenkov cooling of the cluster is effectiv
 e. The possible contribution of neutrino clusters to dark matter is briefl
 y discussed.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6
