The journal Few-Body Systems presents original research work – experimental| theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods| properties| and results characteristic of few-body systems. Examples of few-body systems range from few-quark states| light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems)| up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed| and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions| the journal also encourages interdisciplinary contributions that foster common approaches and insights| introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
