论文摘要
由于1980年代吕沙尔的开创性工作，因此众所周知，考虑有限体积的量子系统，特别是有限的周期盒，可以用作提取物理可观察物的强大计算工具。尽管这种形式主义在两体部门中已经详细介绍了，但目前正在投入很多努力来推导具有更多组成部分的系统的类似关系。这项工作不仅与核物理学相关，核物理学现在可以计算出很少和许多核状状态，而且与其他领域（例如冷原子的模拟）相关。本文讨论了关于从有限数量的成分数量的系统计算中提取几体结合状态和共振属性的最新进展。
Since the pioneering work of Lüscher in the 1980s it is well known that considering quantum systems in finite volume, specifically, finite periodic boxes, can be used as a powerful computational tool to extract physical observables. While this formalism has been worked out in great detail in the two-body sector, much effort is currently being invested into deriving analogous relations for systems with more constituents. This work is relevant not only for nuclear physics, where lattice methods are now able to calculate few- and many-nucleon states, but also for other fields such as simulations of cold atoms. This article discusses recent progress regarding the extraction of few-body bound-state and resonance properties from finite-volume calculations of systems with an arbitrary number of constituents.
