EDIpack: a generic and interoperable Lanczos-based exact diagonalization solver for Quantum Impurity problems
This is the latest version of EDIpack: a Lanczos based method for the solution of generic Quantum Impurity problems, exploiting distributed memory MPI parallelisation. This 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.
EDIpack is available in the form of a static Fortran library (libedipack.a) and the related Fortran module EDIPACK.
The release version includes additional modules to extend the software functionalities: i) an inequivalent impurities extension Edipack2ineq
and ii) a shared dynamical library edipack_cbindings.so implementing the Fortran-C interface.
A standard installation from source is available through CMake, via the standard out-of-source method.
An alternative approach is provided via Anaconda.
Detailed information can be found at edipack.github.io/EDIpack/installation
All the informations about the structure of the library and its use can be found in the documenation at edipack.github.io/EDIpack/
In Quickstart we illustrate the use and the capabilities of EDIpack as a solver for Dynamical Mean-Field Theory calculation.
