玻色子和费米子的超对称在统一粒子物理中不同的基本相互作用方面起着重要作用。由于没有观测到基本粒子的超伴子，超对称性即使存在，也必须在低能处被打破。这使得理解SUSY是如何实现和打破的，并研究其后果变得非常重要。我们证明了anSUSY，可以说是最简单的类型，可以在Moore-Read量子霍尔态的边缘实现。根据有无边缘重构，可以在同一系统中实现SUSY保持相和SUSY破缺相，从而实现对它们的统一描述。讨论了无间隙费米子Goldstino模式在超对称性破缺相中的意义。
Supersymmetry (SUSY) relating bosons and fermions plays an important role in unifying different fundamental interactions in particle physics. Since no superpartners of elementary particles have been observed, SUSY, if present, must be broken at low-energy. This makes it important to understand how SUSY is realized and broken, and study their consequences. We show that anSUSY, arguably the simplest type, can be realized at the edge of the Moore-Read quantum Hall state. Depending on the absence or presence of edge reconstruction, both SUSY-preserving and SUSY broken phases can be realized in the same system, allowing for their unified description. The significance of the gapless fermionic Goldstino mode in the SUSY broken phase is discussed.
