TL;DR
This paper explores a model where large extra dimensions contain many branes, represented as spins indicating preserved supersymmetry directions, leading to a universe with patchwork supersymmetry breaking.
Contribution
It introduces a novel spin system framework to model localized branes in large extra dimensions and their role in supersymmetry breaking.
Findings
Universe's supersymmetry breaking may result from patchwork of different spin orientations.
Localized defects can be modeled as thin domain walls with gravitino mass localization.
Proposes a new approach to understanding supersymmetry breaking in higher-dimensional theories.
Abstract
A very large extra dimension may contain many localized branes. We discuss the possibility to formulate such models as a spin system where each spin indicates the supersymmetry direction preserved by the corresponding brane. In the evolution of the universe, the extra dimensions might have ended into a vacuum made of patches with different orientation of the spins, responsible for the observed breaking of supersymmetry. We discuss the limit where the separation of these patches is by very thin defects described as localization of gravitino masses.
