From electronic structure to elasticity
Jianfeng Lu, CIMS

Ab initio electronic structure models like density functional theory have been widely used in a range of applications. The mathematical understanding of these models is still sparse. In this talk, we will discuss some recent works about the continuum limit of the electronic structure models, trying to build connection between density functional theory and the elasticity theory. Algorithm developed based on the multiscale strategy enables electronic structure calculations for macroscopic systems. (Joint work with Weinan E).
