Fetal brain activity and the free energy principle

Journal of Perinatal Medicine, 2023
Abstract Objectives To study whether the free energy principle can explain fetal brain activity and the existence of fetal consciousness via a chaotic dimension derived using artificial intelligence.

Energy versus free-energy conservation in first-principles molecular dynamics

Physical Review B, 1992
In applying first-principles molecular dynamics to metals, a fictitious temperature is usefully assigned to the electronic (Fermi-Dirac) occupation functions. This avoids instabilities associated with fluctuations in these occupations during the minimization of the energy density functional.

Free Energies and the Dissipation Principle

2011
We present in this chapter an axiomatic formulation of thermodynamics in order to introduce free energies in a very general manner and to prove certain fundamental properties of these quantities. For most of the discussion, no underlying model is assumed, in contrast to the previous chapter.

The free energy principle induces intracellular compartmentalization

Biochemical and Biophysical Research Communications
Living systems at all scales are compartmentalized into interacting subsystems. This paper reviews a mechanism that drives compartmentalization in generic systems at any scale. It first discusses three symmetries of generic physical interactions in a quantum-theoretic description.

Concerning equilibrium, free energy changes, Le Châtelier's principle

Journal of Chemical Education, 1964
Aqueous KI is added to a solution of CuSO4 in a separatory funnel; adding more CuSO4 demonstrates an equilibrium sift.

Minimum-energy principle for a free-boundary, force-free plasma

Plasma Physics and Controlled Fusion, 1986
A variational principle for a cold plasma, formulated by Taylor (1974), minimizes the magnetic energy of a cylindrical plasma confined by a infinitely conducting metal wall, subject to the constraints of constant longitudinal flux and magnetic helicity.
