DESCRIPTION:Speakers: Guilherme Delfino Silva (Purdue University)\n\nIn th
 is talk\, we consider classes of systems that are invariant under modulate
 d symmetries: symmetry operators that act non-uniformly across space\, tog
 ether with their gauging. In one dimension\, gauging these symmetries prov
 ides a concrete pathway to Kramers–Wannier-like dualities and offers ins
 ight into the properties of critical points. More interestingly\, in two d
 imensions\, gauging these symmetries provides a simple and systematic rout
 e to constructing symmetry-enriched topological phases (SETs)\, in which c
 rystalline symmetries enrich the quantum numbers carried by topological an
 yons. Using local spin-lattice Hamiltonians as a concrete setting\, we sho
 w that the resulting gauge theories exhibit modulated string-like symmetri
 es together with mixed anomalies. Throughout the talk\, we illustrate thes
 e ideas using a variety of simple toy models.\n\nhttps://indico.psi.ch/eve
