DOI: 10.1016/j.aop.2019.167922
Abstract: Fractional excitations in fracton models exhibit novel features not present in conventional topological phases: their mobility is constrained, there are an infinitude of types, and they bear an exotic sense of 'braiding'. Hence, they require… read more here.

DOI: 10.1103/physrevb.100.075148
Abstract: Fracton phases of matter host fractionalized topological quasiparticles with restricted mobility. A wide variety of fracton models with Abelian excitations had been proposed and extensively studied while the candidates for non-Abelian fracton phases are less… read more here.

DOI: 10.1103/physrevb.101.054426
Abstract: The quantum robustness of fracton phases is investigated by studying the influence of quantum fluctuations on the X-Cube model and Haah's code, which realize a type-I and type-II fracton phase, respectively. To this end a… read more here.

DOI: 10.1103/physrevlett.130.196601
Abstract: Fracton phases are a particularly exotic type of quantum spin liquids where the elementary quasiparticles are intrinsically immobile. These phases may be described by unconventional gauge theories known as tensor or multipolar gauge theories, characteristic… read more here.
