Superfluid helium as the condensate of bound atoms pairs
arXiv:2001.10856
Abstract
Based upon the hypothesis of simultaneous participation of helium particles in atom(atom) and pair(pair) motions, the proof of Feynman and Bogoliubov formulas validity for elementary excitations spectrum in superfluid helium is carried out with the double mass of particle.
