The statistical physics of nonequilibria

The laws of material equilibria follow a well-known logic: a First Law (conservation); a Second Law (an entropy tendency principle); and Legendre Transforms that give: (i) driving forces (T, p, μ) from observables (U, V,N), and give (ii) fluctuation-response and Maxwell Relations.  In the past, there has been no equivalent logic for Non-Equilibria, such as forces and flows on networks. I will describe such a logic, which we call Caliber Force Theory (CFT).  It requires maximizing path entropies (Maximum Caliber) instead of state entropies.  I will describe some of the new relationships and insights it gives into dynamics.
