Dark energy from Neutrinos and Standard Model Higgs potential

If neutrino mass is a function of the Higgs potential then minimum of the total thermodynamic potential $Ω$ (which is the Higgs potential minus the neutrino pressure) can shift from the standard electro-weak vev $v=246.2$ GeV by a small amount which depends on the neutrino pressure. If the neutrino mass is a very steep function of the Higgs field then the equilibrium thermodynamic potential can act like the dark energy with $ω\simeq -1$. Choosing the neutrino mass as logarithmic function of the Higgs field and a heavy mass scale, we find that the correct magnitude of the cosmological density of the present universe $ρ_λ\simeq (0.002 eV)^4$ is obtained by choosing the heavy mass at the GUT scale.
