Minimization of Gibbs Free Energy as Thermodynamical Variational Principle in TGD Framework

Abstract

Minimization of Gibbs free energy is applied routinely in bio-chemistry as a thermodynamical variational principle. I have however not applied thermodynamical variational principles systematically in TGD inspired quantum biology. My excuse could be that it is not clear whether dark matter as h_eff = n x h₀ phases is in thermal equilibrium with the ordinary matter. Therefore the arguments have been based mostly on energy minimization and make sense thermodynamically at zero temperature limit. In this article I introduce the minimization of Gibbs free energy via an interesting example related to the understanding of the thermal stability of DNA double strand and apply it to water understood as a system involving dark matter as h_eff = n x h₀ phases.
