AI总结:

本文利用分层规范场论和晶格模型系统研究3+1维分形子相的有能隙界面,在X-cube模型及其与toric code模型之间发现多种新型有能隙边界和界面,包括线性子转换、Kramers-Wannier对偶型界面和电磁对偶界面。

摘要:

本工作利用分层规范场论和晶格模型研究3+1维分形子物质相的有能隙界面。我们分析了X-cube模型中的有能隙边界和有能隙界面,以及X-cube模型与toric code模型之间的有能隙界面。这些有能隙界面分为“无装饰”和“有装饰”两类,其中“有装饰”界面具有类似Chern-Simons的附加作用量用于分层规范场。我们发现了许多新的有能隙边界和界面,例如:(1) X-cube模型的一种有能隙边界,其中正交于界面的电线性子变为磁线性子,后者是磁平面子的复合体;(2) 通过规范平面子系统的1-form对称性,在X-cube模型与toric code模型之间构造的Kramers-Wannier对偶型有能隙界面;(3) X-cube模型中的电磁对偶界面,交换电线性子和磁线性子。

英文摘要:

This work investigates the gapped interfaces of 3+1d fracton phases of matter using foliated gauge theories and lattice models. We analyze the gapped boundaries and gapped interfaces in X cube model, and the gapped interfaces between the X-cube model and the toric code. The gapped interfaces are either "undecorated" or "decorated", where the "decorated" interfaces have additional Chern-Simons like actions for foliated gauge fields. We discover many new gapped boundaries and interfaces, such as (1) a gapped boundary for X-cube model where the electric lineons orthogonal to the interface become the magnetic lineons, the latter are the composite of magnetic planons; (2) a Kramers-Wannier-duality type gapped interface between the X-cube model and the toric code model from gauging planar subsystem one-form symmetry; and (3) an electromagnetic duality interface in the X-cube model that exchanges the electric and magnetic lineons.
