TRIQS Solver benchmarks
=======================

This repository provides systematic tests and benchmarks of various impurity solvers
for a set of reference impurity models. We use the Python interface of the
[TRIQS library](https://triqs.github.io/triqs) as a framework.

Each directory fully defines one specific impurity model and contains the following:

* **notebook.ipynb** - IPython Notebook with a description of the impurity model and analysis of results.
* **model.py** - Defines the local Hamiltonian and the hybridization function of the impurity model.
* **scripts** - Contains one script for each applicable impurity solver (e.g. cthyb, pyed, ...).
* **results** - Contains one hdf5 archive for each impurity solver (e.g. cthyb.h5).
		They consist of the results for the Green function and additional solver information.
