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."}],"ddc":["530"],"year":"2023","day":"19","article_processing_charge":"No","date_published":"2023-04-19T00:00:00Z","author":[{"last_name":"Rammelmüller","first_name":"Lukas","full_name":"Rammelmüller, Lukas"},{"first_name":"David","full_name":"Huber, David","last_name":"Huber"},{"first_name":"Artem","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":"https://doi.org/10.21468/SciPostPhysCodeb.12-r1.0","open_access":"1"}],"related_material":{"record":[{"status":"public","id":"13276","relation":"used_in_publication"}]},"department":[{"_id":"MiLe"}],"ec_funded":1,"publisher":"SciPost Foundation","oa":1,"project":[{"name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411"}],"_id":"13275","doi":"10.21468/scipostphyscodeb.12-r1.0","month":"04","title":"Codebase release 1.0 for FermiFCI","oa_version":"Published Version","type":"research_data_reference","citation":{"short":"L.
