近日，英国伦敦国王学院的Neil Lambert及其研究团队取得一项新进展。经过不懈努力，他们揭示了弦理论与M理论的互为倒数的非相对论性解耦极限。相关研究成果已于2024年12月12日在国际知名学术期刊《高能物理杂志》上发表。

该研究团队认为，对于一个p-膜和一个q-膜，如果存在四分之一BPS交叉配置，那么q-膜的世界体积量子场论（QFT）的p-膜解耦极限，必然等于p-膜的世界体积理论的q-膜解耦极限的倒数。这一点在D0-D4和D1-D3系统的案例中得到了明确展示。

作为这一思想的应用，研究人员利用M2-M5系统中的一对倒数极限，来描述六维N=(2,0)理论中相互作用自对偶弦的动力学。研究人员还讨论了对偶引力理论的极限，并利用对称性论证了极限保持了对偶性。

据悉，人们最近意识到，弦理论和M理论中的每个半BPS对象，都关联着保持超对称性的非相对论性解耦极限。

Title: Reciprocal non-relativistic decoupling limits of String Theory and M-Theory

Abstract: It has recently been realised that there are supersymmetry-preserving non-relativistic decoupling limits associated with each half-BPS object in String Theory and M-Theory. We argue that, given a p-brane and a q-brane for which there is a quarter-BPS intersecting configuration, the p-brane decoupling limit of the q-brane’s worldvolume QFT is necessarily equal to the reciprocal q-brane decoupling limit of the p-brane’s worldvolume theory. This is explicitly shown for the cases of the D0-D4 and D1-D3 systems. As an application of this idea, we use the reciprocal pair of limits in the M2-M5 system to describe the dynamics of interacting self-dual strings in the six-dimensional N = (2, 0) theory. We also discuss the limits of the dual gravitational theories and, using symmetries, argue that the duality is maintained by the limits.
