论文摘要
我们构建了一个纯粹的费米原系统，具有自发损坏的超对称性，该系统与物质的分裂相共有共同特征。由于Nambu-Goldstone机制，我们的模型是无间隙的。它显示了由于费米子子系统对称性而引起的“区域法”熵的地面变性。在强耦合极限中，它变成了尼古拉模型的变体，地面堕落性显示了“体积法律”熵。衡量费米子亚系统对称性本身具有t'hooft异常，但是可能的测定理论可能具有fermionic缺陷，而费米子缺陷却是某些空间方向不动的。
We construct a purely fermionic system with spontaneously broken supersymmetry that shares the common feature with a fracton phase of matter. Our model is gapless due to the Nambu-Goldstone mechanism. It shows a ground-state degeneracy with the "Area-law" entropy due to fermionic subsystem symmetries. In the strongly coupled limit, it becomes a variant of the Nicolai model, and the ground-state degeneracy shows the "Volume-law" entropy. Gauging the fermionic subsystem symmetry has an t'Hooft anomaly by itself, but the would-be gauged theory may possess a fermionic defect that is immobile in certain spatial directions.
