Symmetric Fermion Mass Generation as Deconfined Quantum Criticality

Massless (2+1)D Dirac fermions arise in a variety of systems from graphene to the surfaces of topological insulators, where generating a mass is typically associated with breaking a symmetry. However, with strong interactions, a symmetric gapped phase can arise for multiples of eight Dirac fermions....
