What is it about?
The paper is about an intriguing approach to a classical problem: predicting the path and speed of a process from information about the energy of the process steps. The approach separates the problem into two independent components. The first calculates an energy landscape, and the second uses an equation of motion in a thermodynamic state space to predict the path and rate. The approach is demonstrated with a computational simulation that predicts polymer chain folding during heating and cooling.

Why is it important?
The work combines thermodynamics and kinetics in a mathematically rigorous, self-consistent framework. It does not assume any underlying kinetic mechanisms, transport laws, or local-equilibrium. Since the framework is free of many common assumptions, it is general and has wide-ranging applications to the study of time-dependent behavior in non-equilibrium materials.
