Emergent fracton dynamics in a nonplanar dimer model
Johannes Feldmeier, Frank Pollmann, Michael Knap
Abstract
Lattice gauge theories describe strongly interacting quantum many-body systems whose nonequilibrium properties in more than one dimension provide a challenge to current numerical methods. Here, the authors study a dimer model as an example of a U(1) gauge theory whose universal transport properties can be extracted using classically simulable methods. This is achieved by exploiting a surprising connection to topological solitons, enabling a venue of analysis that demonstrates how gauge constraints induce fractonic mobility, slow subdiffusive transport, and nonergodic dynamics.
