QuEmb

QuEmb is a robust framework designed to implement the Bootstrap Embedding (BE) method, efficiently treating electron correlation in molecules, surfaces, and solids. This repository contains the Python implementation of the BE methods, including periodic bootstrap embedding. The code leverages PySCF library for quantum chemistry calculations and utlizes Python’s multiprocessing module to enable parallel computations in high-performance computing environments.

QuEmb includes two libraries: quemb.molbe and quemb.kbe. The quemb.molbe library implements BE for molecules and supramolecular complexes, while the quemb.kbe library is designed to handle periodic systems such as surfaces and solids using periodic BE.
