Optimal free descriptions of many-body theories

Optimal free descriptions of many-body theories

Physicists’ understanding of interacting many-body systems often depends on finding an approximate description in terms of non-interacting particles. Here, the authors propose a systematic approach to identify the closest free particle description of a given model.
