摘要

我们在数值原子轨道线性组合(LCNAO)框架内提出了电荷自洽动态均场理论(DMFT)与密度泛函理论(DFT)相结合的形式主义。我们通过将全电势全电子 DFT 代码与三个基于杂化扩展的连续时间量子蒙特卡洛杂质求解器连接起来,实现了电荷自洽 DFT+DMFT 形式。几个 3d、4f 和 5f 强相关电子系统的基准测试验证了我们的形式主义和实现。此外,在 LCANO 框架内,我们的形式主义是通用的,代码架构是可扩展的,因此它可以作为一座桥梁,将不同的 LCNAO DFT 软件包和杂质求解器合并起来,进行电荷自洽的 DFT+DMFT 计算。

Charge Self-consistent Dynamical Mean Field Theory Calculations in Combination with Linear Combination of Numerical Atomic Orbitals Framework based Density Functional Theory
We present a formalism of charge self-consistent dynamical mean field theory (DMFT) in combination with density functional theory (DFT) within the linear combination of numerical atomic orbitals (LCNAO) framework. We implemented the charge self-consistent DFT+DMFT formalism by interfacing a full-potential all-electron DFT code with three hybridization expansion-based continuous-time quantum Monte Carlo impurity solvers. The benchmarks on several 3d, 4f and 5f strongly correlated electron systems validated our formalism and implementation. Furthermore, within the LCANO framework, our formalism is general and the code architecture is extensible, so it can work as a bridge merging different LCNAO DFT packages and impurity solvers to do charge self-consistent DFT+DMFT calculations.
