Journal Title：Few-body Systems

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).

Few-Body Systems 期刊展示了原始研究工作——实验、理论和计算——调查由少量定义明确的组成结构组成的任何经典或量子系统的行为。重点是少体系统的研究方法、性质和结果特征。少体系统的例子包括少夸克态、轻核和强子系统；少电子原子系统和小分子；以及凝聚态和表面物理学中的特定系统（例如量子点和高度相关的陷阱系统），直至并包括大型天体结构。

具有或可以设计等效单体描述的系统，以及需要特定多体方法的大型系统不在期刊的范围内。

该杂志致力于出版少体系统研究和应用的各个方面。在专注于非常适合严格解决方案的少体系统的同时，该杂志还鼓励跨学科贡献，以培养共同的方法和见解，介绍和基准测试新工具（例如机器学习）的使用并开发相关应用程序（例如少体方面）量子技术）。
