报告摘要：Both experimental and numerical works in recent years have shown that thermal conductivity due to phonons in low dimensional nano scale systems like nanotube, nanowire, polymer chain, graphene, and other 2D materials are size dependent. In this talk, I will present a general theoretical understanding of the anomalous thermal conductivity. More specifically, I will discuss how the anomalous thermal transport (a macroscopic phenomenon) is connected with the anomalous heat diffusion (a microscopic process).
