Power functional theory for many-body dynamics

In equilibrium, the unifying framework of density-functional theory provides a variational scheme to determine both thermodynamics and correlation functions classical systems in presence an external potential field. Density-functional has found range application nowadays forms central pillar liquid state soft matter theory. Given many successes it is natural seek approach treat out equilibrium. This was achieved with development power functional review describes theory, which based on exact one-body principle describe dynamics overdamped, inertial classical, quantum many-body systems.
