nrgljubljana_iterface provides C++ and Python interfaces between TRIQS and the NRG Ljubljana solver.
“NRG Ljubljana” is a general-purpose flexible framework for performing large scale numerical renormalization group (NRG) calculations for quantum impurity problems. It is highly extensible without sacrificing numerical efficiency. It supports a great variety of impurity Hamiltonians and symmetry types. More details can be found on the project homepage, while the code itself is hosted on Github.
