DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/35/">
 Higgs condensates are symmetry-protected topological phases: from cluster 
 states to superconductors</a>\nby Ruben Verresen (Harvard) as part of Symm
 etry Seminar\n\n\nAbstract\nDeconfined phases of gauge theories are now we
 ll-understood as spontaneously breaking higher-form symmetries. How does t
 he Higgs phase fit in this way of thinking? In this talk\, we will explore
  how the Higgs phase does not just preserve such a higher-form symmetry\, 
 but is in a non-trivial symmetry-protected topological (SPT) phase. This s
 heds new light on the distinction between confined and Higgs phases. In fa
 ct\, the remarkable properties of superconductors---which are Higgs phases
  for U(1) gauge theory---can be derived as SPT properties! This is based o
 n the works arxiv:2010.00607\, arxiv:2211.01376 and arxiv:2303.08136.\n
