Abstract

This talk briefly introduces the ubiquitous natural phenomena: heterogeneous and nonergodic diffusion, and its various applications. Then we discuss the microscopic models describing the heterogeneous and nonergodic diffusion and derive the PDEs governing the probability density function of some useful/interesting statistical observables (say, functionals). Finally, we talk about the numerical issues for the newly derived PDEs.
