开始接触正规的DFT软件，重点关注代码实现，不必深究物理细节

学完这个记得去看GPAW（gitlab仓库已fork，内核不会变，无需更新），充分理解后，可以考虑看非python写的软件包的源码

What I cannot create, I do not understand. - Richard Feynman

The overall goal of the Psi4NumPy project is to provide an interactive quantum chemistry framework for reference implementations, rapid prototyping, development, and education. To do this, quantities relevant to quantum chemistry are computed with the Psi4 electronic structure package, and subsequently manipulated using the Numerical Python (NumPy) package. This combination provides an interface that is both simple to use and remains relatively fast to execute.

A series of short scripts demonstrating the implementation of Hartree-Fock Self-Consistent Field, SCF Response, Møller-Plesset Perturbation Theory, Symmetry-Adapted Perturbation Theory, Coupled Cluster Theory, and more are provided for the reference of the quantum chemistry community at large to facilitate both reproducibility and low-level methodological understanding. Additionally, the Tutorials folder above represents an interactive educational environment containing modules discussing the theory and implementation of various quantum and computational chemistry methods. By leveraging the popular Jupyter Notebook application, each tutorial is constructed as hybrid theory and programming in an easy to use interactive environment, removing the gap between theory and implementation.

If you have comments, questions, or would like to contribute to the project please see our contributor guidelines.

在linux上，直接conda安装即可（不需要登录anaconda）

conda create -n p4env psi4 -c psi4

windows上，先禁用镜像，然后

conda create -n p4env psi4 python=3.8 -c conda-forge/label/libint_dev -c conda-forge

This repository contains

• reference implementations, which provide working Python scripts implementing various quantum chemical methods, and
• interactive tutorials, which provide Jupyter notebooks presenting a hybrid theory-and-implementation educational framework for learning to program quantum chemistry methods.

Reference implementations are organized into top-level directories corresponding to the over-arching theory upon which each method is based, i.e., both EOM-CCSD and TD-CCSD are contained in the Coupled-Cluster directory. All interactive tutorials are contained in the top-level directory Tutorials. These tutorials are organized in logical order of progression, which is enumerated in detail here.

This repostitory has recently been updated to be compatible with Psi4 version 1.1. Please see the v0.1-beta tag for a Psi4 v1.0 compliant Psi4NumPy version.

This reposititory is fully compatible with the upcoming Psi4 version 1.2. In fact (for a while), if you use v1.2, there's no need to worry if your Psi4 has all the features to run all the reference implementations and tutorials.
