Exotic Symmetries, Duality, and Fractons in 3+1-Dimensional Quantum Field Theory

arXiv:2004.06115 · doi:10.21468/SciPostPhys.10.1.003

Abstract

Following our earlier analyses of nonstandard continuum quantum field theories, we study here gapped systems in 3+1 dimensions, which exhibit fractonic behavior. In particular, we present three dual field theory descriptions of the low-energy physics of the X-cube model. A key aspect of our constructions is the use of discontinuous fields in the continuum field theory. Spacetime is continuous, but the fields are not.
