More Exotic Field Theories in 3+1 Dimensions

Understand

We continue the exploration of nonstandard continuum field theories related to fractons in 3+1 dimensions.

• Our theories exhibit exotic global and gauge symmetries, defects with restricted mobility, and interesting dualities.
• Depending on the model, the defects are the probe limits of either fractonic particles, strings, or strips.
• One of our models is the continuum limit of the plaquette Ising lattice model, which features an important role in the construction of the X-cube model.
