# EDIpack2.0: Massively parallel Exact Diagonalization for generic Quantum Impurity problems
[](https://github.com/aamaricci/EDIpack2.0/actions/workflows/PushWorkflow.yml)
[](https://aamaricci.github.io/EDIpack2.0/)
A suitable extension of [EDIpack](https://github.com/aamaricci/EDIpack): a Lanczos based method
for the solution of generic Quantum Impurity problems, exploiting distributed memory MPI parallelisation.
This updated version, aims to solve single-site, multi-orbital models, in either *normal*, *superconducting* (s-wave) or *Spin-non-conserving* (e.g. with Spin-Orbit Coupling or in-plane magnetization) phases, including electron-phonons coupling. The code works at zero and low temperatures.
See [j.cpc.2021.108261](https://doi.org/10.1016/j.cpc.2021.108261) for further information about the underlying algorithms. Yet, suitable modifications have been developed to address the Superconducting and non-SU(2) channels.
### Install & Use
*EDIpack2.0* builds and get installed using CMake. Loading into the operative systemisis provided by different methods, including module environment.
Further informations and a guided proceudre are available in the documentation.
### Documentation
All the informations about the structure of the library and its use, together with the Python API *EDIpy2*, are documented at [aamaricci.github.io/EDIpack2.0/](https://aamaricci.github.io/EDIpack2.0/)
NOTE: The documentation is currently under construction.
