Our aim is to provide a testbed for the newcomers to the field as well as a stepping stone for trying out novel optimizations and approximations. This userguide consists of a description of the algorithm, and several examples in varying orders of sophistication. In particular, we exemplify our routine using an effective-interaction approach that fixes the low-energy physics. We benchmark this approach against the existing data, and show that it is able to deliver state-of-the-art numerical results at a significantly reduced computational cost."}],"author":[{"last_name":"Rammelmüller","full_name":"Rammelmüller, Lukas","first_name":"Lukas"},{"first_name":"David","last_name":"Huber","full_name":"Huber, David"},{"first_name":"Artem","orcid":"0000-0003-0393-5525","last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem"}],"related_material":{"record":[{"id":"13276","relation":"used_in_publication","status":"public"}]},"citation":{"mla":"Rammelmüller, Lukas, et al.
