What are... Reaction Fluxes?

As usual in thermodynamics (and many SFB1114 projects), chemical reaction networks can be studied on at least two different scales: a microscopic system of randomly reacting particles, and macroscopic concentrations that follow the path of minimal action. Mathematically, the challenge is to bridge both levels of description, and to study further scaling limits using the action functional. Physically, one can study the action to derive thermodynamic properties of the system. Our main philosophy is that both mathematically and physically, it is beneficial to take more information into account than just the concentrations...
