"The Statistical Mechanics of Driven Nonequilibrium Systems: Theoretical Approaches"
In modeling statistical systems away from thermal equilibrium one usually starts with a definition of the microscopic dynamics, e.g., in terms of transition rates, and then derives the resulting macroscopic behavior. In the main part of this talk I address the inverse question for a class of steady state systems, namely complex fluids under continuous shear flow: how does an externally imposed shear current affect the microscopic dynamics of the complex fluid? Based on a nonequilibrium ensemble theory one can formulate the answer as exact relations for the transition rates in the nonequilibrium steady state. These relations can be considered as a nonequilibrium counterpart to the principle of detailed balance. Furthermore, I discuss a stochastic model for self-propulsion on a featureless track, which serves as a unifying model for the propulsion mechanism of various motor proteins.
