Power functional theory in a nutshell
A comprehensive account of power functional theory for many-body
dynamics is in
Rev. Mod. Phys.
94, 015007 (2022). The theory describes
the dynamics of particle-based many-body systems. It is based
on an exact variational principle, akin to density functional
theory and closely related to Gibbs-Appell-Gaussian classical
mechanics.
See the UBT press release here (German version).
Physical systems range from self-propelled active Brownian
particles, shear and flow phenomena in colloids and
liquids, to the microscopic structure on the particle scale.
Forces are at the fore and systematically classified
into adiabatic (free energy-like) and superadiabatic
(genuine nonequilibrium) contributions, viscous and structural
nonequilibrium forces, and according to their functional density-,
velocity- and acceleration-dependence. The theory allows to
exploit Noether's theorem in statistical
mechanics.
