A Rheological Approach to the Viscous Fermionic Vacuum Condensate

This paper presents a phenomenological model of the physical vacuum as a macroscopic quantum state — a viscous fermionic condensate (VFC). We hypothesize the existence of a fundamental dynamic viscosity coefficient of the medium, η ≈ 1.2 × 10^−15 Pa·s. A phase transition from a superfluid to a viscous state at an energy threshold of 7.76 keV is discussed. This approach directly derives elementary particle mass from the hydrodynamic drag of the medium during the motion of topological solitons.
