  • Reduced density matrix functional theory for periodic systems

    6th ABACUS Developers' Meeting · Hefei, China · Aug 2026

    Abstract摘要

    Reduced density matrix functional theory (RDMFT) offers a route beyond standard Kohn–Sham DFT by treating the one-particle reduced density matrix as the basic variable, with natural occupations that can capture strong correlation. I will discuss recent progress on formulating and implementing RDMFT for periodic solids, including practical choices for functionals, occupation and natural orbital optimization, and connections to plane-wave and numerical atomic-orbital frameworks relevant to ABACUS.
