Fractonic topological phases

Abstract / Résumé :
Recently a new type of gapped phases was discovered in (3+1) dimensions, whose unusual properties appear to defy a conventional QFT description. Notably, they support quasiparticles with reduced mobility, sometimes completely immobile, and have an exponentially large number of locally indistinguishable ground states on a three torus. In this talk I will review basic facts about fracton models, and discuss recent progress in understanding general structures of fractonic phases.
