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."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.21468/scipostphyscodeb.12-r1.0","year":"2023","article_processing_charge":"No","oa":1,"title":"Codebase release 1.0 for FermiFCI","date_published":"2023-04-19T00:00:00Z","citation":{"short":"L.
