n维自反多面体由于其与范诺n-折叠和镜像对称的关系,在数学和理论物理中引起了广泛的关注。本研究的重点是18个对应于光滑Fano 3-fold的规则自反多面体。我们首次证明了所有18个正则自反多面体都有对应的由膜砖模型实现的2d(0,2)规范理论。这些二维规范理论可以看作是d1膜的世界体积理论,它们探测到其环面图由相关的正则自反多面体给出的环面Calabi-Yau - 4奇点。膜砖模型的介子模空间的产生子由于在3阶介子风味对称下的电荷而形成了一个产生子晶格。证明了发生器晶格是膜砖模型对应的环图的精确极性对偶自反多面体。这种对偶性不仅突出了几何和二维规范理论之间的密切关系,而且为反身多面体和膜砖模型的新发现开辟了道路。
Reflexive polytopes in n dimensions have attracted much attention both in mathematics and theoretical physics due to their connection to Fano n-folds and mirror symmetry. This work focuses on the 18 regular reflexive polytopes corresponding to smooth Fano 3-folds. For the first time, we show that all 18 regular reflexive polytopes have corresponding 2d (0, 2) gauge theories realized by brane brick models. These 2d gauge theories can be considered as the worldvolume theories of D1-branes probing the toric Calabi-Yau 4-singularities whose toric diagrams are given by the associated regular reflexive polytopes. The generators of the mesonic moduli space of the brane brick models are shown to form a lattice of generators due to the charges under the rank 3 mesonic flavor symmetry. It is shown that the lattice of generators is the exact polar dual reflexive polytope to the corresponding toric diagram of the brane brick model. This duality not only highlights the close relationship between the geometry and 2d gauge theory, but also opens up pathways towards new discoveries in relation to reflexive polytopes and brane brick models.
