Efficient Bethe-Salpeter Equation Calculations Based on Numerical Atomic Orbitals and Norm-Conserving Pseudopotentials: Dual--Mesh Strategy
Ziqing Guan, Yu Cao, Min-Ye Zhang +3
We present an efficient implementation of the Bethe--Salpeter equation (BSE) based on numerical atomic orbitals (NAOs) and norm-conserving pseudopotentials within the ABACUS+LibRPA…
Low-scaling \textit{GW} calculations of quasi-particle energies for extended systems within the numerical atomic orbital framework
Min-Ye Zhang, Peize Lin, Rong Shi +1
The many-body perturbation theory within the approximation is a widely used method for describing the electronic band structures in real materials. Its application to large-sc…
Real-time time-dependent density functional theory simulations with range-separated hybrid functionals for periodic systems
Yuyang Ji, Haotian Zhao, Peize Lin +2
Real-time time-dependent density functional theory (RT-TDDFT) is a powerful approach for investigating various ultrafast phenomena in materials. However, most existing RT-TDDFT stu…
ABACUS: An Electronic Structure Analysis Package for the AI Era
Weiqing Zhou, Daye Zheng, Qianrui Liu +55
ABACUS (Atomic-orbital Based Ab-initio Computation at USTC) is an open-source software for first-principles electronic structure calculations and molecular dynamics simulations. It…
