Conformality loss and quantum criticality in topological Higgs electrodynamics in 2+1 dimensions
Nogueira, Flavio S.; van den Brink, Jeroen; Sudbø, Asle (Journal article; Peer reviewed, 2019)The electromagnetic response of topological insulators and superconductors is governed by a modified set of Maxwell equations that derive from a topological Chern-Simons (CS) term in the effective Lagrangian with coupling ...
