| 摘 要： | Fractonic superfluids are exotic states of matter with spontaneously broken higher-rank U(1) symmetry.The broken symmetry is associated with conserved quantities,including not only particle number(i.e.,charge) but also higher moments,such as dipoles,quadrupoles,and angular moments.Owing to the presence of such conserved quantities,the mobility of particles is restricted either completely or partially.Here,we systematically study the hydrodynamical properties of fractonic superfluids,especially f...
