SCAN Density Functional: Fundamentals, Practices, and Extensions Workshop
Density functional theory (DFT) is one of the most widely used electronic structure theories in chemistry, condensed matter physics, and materials science. This workshop will focus on a recent breakthrough in DFT, the strongly-constrained and appropriately-normed (SCAN) meta-generalized gradient approximation (meta-GGA). SCAN predicts accurate geometries and energies of diversely-bonded molecules and materials (including covalent, metallic, ionic, hydrogen, and van der Waals bonds), significantly improving over its predecessors, at comparable efficiency, the GGAs that dominate materials computation. Remarkably, SCAN often matches or improves upon the accuracy of a computationally expensive hybrid functional, at almost-GGA cost.
This one-day workshop will invite world-leading experts to talk about the fundamentals of DFT, basic ideas behind the construction of SCAN and its potential impacts, as well as its possible extensions. Graduate students and junior researchers will also have the chance to attend hand-on sessions to learn how to use SCAN to obtain geometric, energetic, electronic, vibrational, and dynamic properties of materials (the main software used are VASP and PHONOPY). The invited speakers include John Perdew, Michael Klein, Adrienn Ruzsinszky, Weitao Yang, Alejandro Garza, Kieron Burke, Xifan Wu, Torsten Hahn, Jing Yang, Yubo Zhang, Haowei Peng, Liping Yu, Richard Remsing, and Jianwei Sun.
