"Comments on abelian Higgs models and persistent order" by Zohar Komargodski, Adar Sharon, Ryan Thorngren and Xinan Zhou has received the Select label. Warm congratulations to the authors!



This paper deals with the question regarding deformations of trivial gapped phases within Quantum Field Theory. In fact, it gives an interesting demonstration of the fact that even simple bosonic systems can have anomalies of discrete symmetries. The existence of anomalies implies that the theory cannot be completely disordered with a trivial gapped phase without topological order. The authors specifically connect these results with possible strong coupling regions. Finally, the authors discuss the important implications regarding whether the symmetries can be disordered or not. The models they discuss also are relevant to condensed matter systems.
