LOSC is a newly developed method in Weitao Yang's Research group to solve the delocalization error for the density functional theory (DFT) in quantum chemistry.
- This project provides libraries with interfaces for popular programming languages in quantum chemistry, including C, C++ and Python, for the developers who would be interested to implement the LOSC method in their favorite quantum chemistry packages. These libraries provide the functionalities to perform the essential calculations of the LOSC method, such as constructing the LOs, LOSC curvature matrix, and LOSC corrections.
- This project provides the implementation of LOSC method in an open-source quantum chemistry package, psi4, with its Python interface. If you are a user of psi4, you can directly use this library with psi4 to perform LOSC calculations.
The manual and documentation are available at https://yang-laboratory.github.io/losc/. Refer to the website for the instructions of installation and usage.
