Superfluidity as sequence of an ordering of zero-point oscillations
  The phenomenon of superconductivity was explained as a consequence of ordering of zero-point oscillations. Superfluidity are related phenomenon. The consideration of interaction zero-point oscillations in liquid helium permit to obtain quantitative estimations of main characteristic of superfluid helium which are in a good agreement with measuring data. So both related phenomena, superconductivity and superfluidity, get explanation which is based on the same physical mechanism - they both are consequences of the ordering of zero-point oscillations.
