Solvers for Large-Scale Electronic Structure Theory: ELPA and ELSI
Petr Karpov, Andreas Marek, Tobias Melson +14
In this contribution, we give an overview of the ELPA library and ELSI interface, which are crucial elements for large-scale electronic structure calculations in FHI-aims. ELPA is…
All-electron BSE@GW method with Numeric Atom-Centered Orbitals for Extended Systems
Ruiyi Zhou, Yi Yao, Volker Blum +2
Green's function theory has emerged as a powerful many-body approach not only in condensed matter physics but also in quantum chemistry in recent years. We have developed a new all…
Efficient All-electron Hybrid Density Functionals for Atomistic Simulations Beyond 10,000 Atoms
Sebastian Kokott, Florian Merz, Yi Yao +6
Hybrid density functional approximations (DFAs) offer compelling accuracy for ab initio electronic-structure simulations of molecules, nanosystems, and bulk materials, addressing s…
Enhancing Reduced Density Matrix Functional Theory Calculations by Coupling Orbital and Occupation Optimizations
Yi-Fan Yao, Neil Qiang Su
Reduced density matrix functional theory (RDMFT) calculations are usually implemented in a decoupled manner, where the orbital and occupation optimizations are repeated alternately…
