Screw dislocations in the X-cube fracton model

Understand

The X-cube model, a prototypical gapped fracton model, has been shown to have a foliation structure.

• That is, inside the 3+1D model, there are hidden layers of 2+1D gapped topological states.
• A screw dislocation in a 3+1D lattice can often reveal nontrivial features associated with a layered structure.
• In this paper, we study the X-cube model on lattices with screw dislocations.
