摘要：
A very large extra dimension may contain many localized branes. We discuss the possibility of formulating such models as a spin system where each spin indicates the supersymmetry (SUSY) direction preserved by the corresponding brane. In the evolution of the universe, the extra dimensions might have ended up as a vacuum made of patches with different orientations of the spins, responsible for the observed breaking of SUSY. We discuss the limit where the separation of these patches is by very thin defects, described as localization of gravitino masses.
