 ">Volume preserving diffeomorphism as a higher-rank gauge symmetry</a>\nby
  Dam Son (Chicago) as part of CCTP HEP Seminars\n\n\nAbstract\nRecently\, 
 theories with higher rank gauge symmetries are drawing attention in conden
 sed matter physics. Such theories are thought to be related to the so-call
 ed "fractons\," quasiparticles with limited mobility that appear in some l
 attice models. We show that one version of such higher ranked symmetry can
  be "nonlinearlized" into volume-preserving diffeomorphism. We demonstrate
  that several condensed matter systems\, including the fractional quantum 
 Hall effect and ferromagnetism\, secretly possess this symmetry\, which sh
 eds another light to some peculiar features of the quasiparticles in these
  systems.\n
