Disordered Reactive Transport: From Microscopic Description to Mesoscopic Understanding

Spatial and temporal inhomogeneities in transport and reaction at the nanoscale can have a marked influence on observables at larger scales. State-of-the art experimental methods allow characterizing stochastic nanoscale events, such as translations andreactions, with high spatial and temporal resolution. This nanoscale disorder is widespread in both inorganic and biological systems. It takes manifold forms, including spatially random constituents, as well as random conformational dynamics. The knowledge gained poses the theoretical challenge of finding mesoscopic descriptions that not only reproduce some aspects of bulk behavior, but also are consistent with, and elucidate, the emerging understanding of the microscopic transport and kinetics. We present some recent theoretical progress, and highlight the role of stochastic frameworks including the continuous time random walk, first passage under reset, and renewal theory.
