AI 中文摘要
我们提出两个相关的定制软件包Hubb_DMFT和Wan2mb_DMFT，用于求解强关联电子系统的动力学平均场理论（DMFT）方程。Hubb_DMFT针对单带哈伯德模型进行了调整，提供了一种快速计算局域自能以及两粒子费米子、三角费米子-玻色子电荷和自旋顶点的方法；而Wan2mb_DMFT将该能力扩展到实际的多轨道系统，直接将Wannier紧束缚哈密顿量与多体求解器对接。两个代码均基于iQIST v.0.7杂质求解器，采用经修改并内部集成的连续时间量子蒙特卡洛（CT-QMC）核心，结合杂化展开（CT-HYB）框架以及针对密度-密度相互作用的改进自能和顶点估计器，确保量子杂质问题的数值精确解。
英文摘要
We present two related customized software packages, Hubb_DMFT and Wan2mb_DMFT, designed to solve the Dynamical Mean-Field Theory (DMFT) equations for strongly correlated electron systems. Hubb_DMFT is adjusted for the single-band Hubbard model, providing a fast way to calculate the local self-energy, as well as the two-particle fermion and triangular fermion-boson charge and spin vertices, while Wan2mb_DMFT extends this capability to realistic multi-orbital systems, directly interfacing Wannier tight-binding Hamiltonians with many-body solvers. Both codes are based on iQIST v.0.7 impurity solver and utilize a modified and internally integrated Continuous-Time Quantum Monte Carlo (CT-QMC) core with the hybridization expansion (CT-HYB) framework and improved self-energy and vertex estimators for density-density interaction, ensuring numerically exact solutions for quantum impurity problems.
