报告摘要:

Python package PySCF was initiated to supporting quantum embedding theory. During the development of PySCF package, this project was directly or indirectly involved into various novel quantum chemistry methodologies, including but not limited to density matrix embeddings, matrix product states and tensor network states, quantum Monte Carlo, selected Configuration interactions, quantum neural network states, deep neural network for chemistry and Shrodinger equations. Unlike the traditional first principle methodologies which have particularly strict mathematical frameworks and deterministic computational algorithms, these newly proposed quantum chemistry models stands at the other end that utilizes in the model more physical insights or stochastic characters of the many body systems. Along with the methodology development, new computing and programming technologies were also employed or developed. Single-side MPI (message passing interface) implementation, distributed memory tensor contraction engine CTF were used.
