The non-empirical parameter-free strongly constrained and appropriately normed (SCAN) meta-GGA is believed to be the state-of-the-art efficient semilocal density functional. Its performance keeps on bringing new surprises even to its developers. In this talk, we report our recent work on testing SCAN for the energetic, electronic, magnetic, and vibrational properties of wide classes of materials.By studying ~300 binary compounds, we show SCAN has advanced to a point where chemical stability, i.e., whether a stoichiometry will persist in some chemical environment, and structure selection, i.e., what crystal structure a stoichiometry will adopt, can be reliably and efficiently predicted for main group compounds, while transition metal compounds are improved but remain a challenge. By studying the prototypical ferroelectric materials including BaTiO3 and PbTiO3, we show SCAN significantly improves over the traditional local density approximation (LDA) and the generalized gradient approximation (GGA) for the structural and vibrational properties. Finally, SCAN’s excellent performance on cuprate superconductors, traditionally regarded as strongly-correlated systems out of reach of DFT, will be highlighted, exemplified by its accurate prediction of the metal-insulator transition of La2CuO4 under doping and a successful prediction of the stripe states. Such excellent performance establishes SCAN a robust model for a significant portion of the periodic table, presenting an opportunity for the development of novel materials (including complex correlated materials like cuprates) and the study of fine phase transformations even in largely unexplored systems with little to no experimental data.
