Abstract:
Quantum electrodynamics in (2+1) D (QED_3) consists of relativistic Dirac fermions strongly interacting with photons. Quantum magnets and electron systems under magnetic fields, meanwhile, represent 2 correlated paradigms in magnetism. We show that from symmetry reasoning, QED_3 emerges as a robust, critical phase both in triangular spin-1/2 magnets (called Dirac spin liquid), and half-filled Chern bands of electrons under periodic magnetic fields.
