有限体积中运动束缚态的拓扑相位
Topological phases for bound states moving in a finite volume
摘要：
我们证明了在有限周期体积中运动的束缚态具有能量修正，这种能量修正是拓扑起源的，并且具有普适性质。拓扑体积修正包含有关束缚态组分的数量和质量的信息。这些结果在核子、原子核、强子分子和冷原子的晶格计算中有广泛的应用。我们用几个数值晶格计算来说明和验证分析结果。
英文摘要：
We show that bound states moving in a finite periodic volume have an energy correction which is topological in origin and universal in character. The topological volume corrections contain information about the number and mass of the constituents of the bound states. These results have broad applications to lattice calculations involving nucleons, nuclei, hadronic molecules, and cold atoms. We illustrate and verify the analytical results with several numerical lattice calculations.
