在超引力膜解的背景下，我们讨论了一种通过利用打破对称性的特定方式来引入任何自旋的集体模式的通用方法。该方法应用于 D3、M2 和 M5 膜，我们推导了零模式如何进入目标空间场的显式表达式，验证了横向的归一性，并推导了膜上相应的场方程。特别是，该方法提供了对标量、旋量和 r 阶张量戈德斯通模式、手性和非手性以及它们如何分别从重力、Rarita-Schwinger 和 r+1 Kalb-Ramond 张量规范场产生的清晰理解。讨论了有关 M5 膜上手性张量模式的一些其他观察结果。
In the context of brane solutions of supergravity, we discuss a general method to introduce collective modes of any spin by exploiting a particular way of breaking symmetries. The method is applied to the D3, M2 and M5 branes and we derive explicit expressions for how the zero-modes enter the target space fields, verify normalisability in the transverse directions and derive the corresponding field equations on the brane. In particular, the method provides a clear understanding of scalar, spinor, and rank r tensorial Goldstone modes, chiral as well as non-chiral, and how they arise from the gravity, Rarita-Schwinger, and rank r+1 Kalb-Ramond tensor gauge fields, respectively. Some additional observations concerning the chiral tensor modes on the M5 brane are discussed.
