报告摘要：

A host of diverse phenomena, such as ecological systems, population dynamics, chemical reactions, super-conductivity, quantum dynamics and fluid dynamics, can be modelled by interacting particle systems. A principal theme in investigating these phenomena is to connect the microscopic mechanisms of the systems with the collective behaviors that emerge in the macroscopic scale under suitable space-time scaling. The mathematical theory for the connections is through the hydrodynamic limits (described by PDEs) and the fluctuation limits (described by stochastic PDEs). In this talk, I will present a brief survey and ilustrate these fascinating connections through two concrete models: heat propagations in Euclidean space as well as in rooms, and the transports of positive and negative charges in solar cells.
