TL;DR
This paper explores superfluid helium as a condensate of bound atom pairs, providing theoretical proof for the elementary excitations spectrum using Feynman and Bogoliubov formulas with a double mass approach.
Contribution
It introduces a novel hypothesis of simultaneous atom and pair motions and validates the excitation spectrum formulas for superfluid helium under this framework.
Findings
Feynman and Bogoliubov formulas are valid for superfluid helium
Elementary excitations spectrum can be derived with double mass consideration
Supports the atom-pair participation hypothesis in superfluid helium
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.
