Foliated fracton order in the checkerboard model
Wilbur Shirley, Kevin Slagle, Xie Chen
In this work, we show that the checkerboard model exhibits the phenomenon of foliated fracton order. We introduce a renormalization group transformation for the model that utilizes…
Fractional excitations in foliated fracton phases
Wilbur Shirley, Kevin Slagle, Xie Chen
Fractional excitations in fracton models exhibit novel features not present in conventional topological phases: their mobility is constrained, there are an infinitude of types, and…
Foliated fracton order from gauging subsystem symmetries
Wilbur Shirley, Kevin Slagle, Xie Chen
Based on several previous examples, we summarize explicitly the general procedure to gauge models with subsystem symmetries, which are symmetries with generators that have support…
Information scrambling in chaotic systems with dissipation
Yong-Liang Zhang, Yichen Huang, Xie Chen
Chaotic dynamics in closed local quantum systems scrambles quantum information, which is manifested quantitatively in the decay of the out-of-time-ordered correlators (OTOC) of loc…
Fracton topological order from Higgs and partial confinement mechanisms of rank-two gauge theory
Han Ma, Michael Hermele, Xie Chen
Fractons are gapped point-like excitations in topological ordered phases whose motion is constrained. They have been discovered in several gapped models but a unifying physic…
