DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/134/">
 Aspects of locality\, unitarity\, and symmetries</a>\nby Ibrahima Bah (Joh
 ns Hopkins University) as part of NHETC Seminar\n\n\nAbstract\nIn this tal
 k\, I will explore some aspects of the apparent tension between locality a
 nd unitarity for symmetries in quantum field theory. I will then discuss h
 ow locality can impose regularity conditions on the Hilbert space\, and us
 e this to define an observable that measures the non-locality of symmetry 
 operators. In examples\, this observable encodes data about the fusion alg
 ebra of the symmetries.\n
