论文摘要
我们研究了Chamon模型在具有边界的歧管中描述的分裂阶段。在边界处出现的新过程和激发可以通过图表框架来理解。从连续的角度来看，边界理论由一组与标准$ k $ -mtrix chern-simons理论相似的标量字段描述。一旦我们包含了充分的强大相互作用，可以打破电荷保护，连续理论就恢复了晶格模型的狭窄边界。对领先相互作用的扰动相关性的分析揭示了一个制度，在该方案中，Chamon模型可以在其边界处具有稳定的无间隙分正相。
We study the fracton phase described by the Chamon model in a manifold with a boundary. The new processes and excitations emerging at the boundary can be understood by means of a diagrammatic framework. From a continuum perspective, the boundary theory is described by a set of scalar fields in similarity with the standard $K$-matrix Chern-Simons theory. The continuum theory recovers the gapped boundaries of the lattice model once we include sufficiently strong interactions that break charge conservation. The analysis of the perturbative relevance of the leading interactions reveals a regime in which the Chamon model can have a stable gapless fractonic phase at its boundary.
