DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/16/">
 Defects and higher symmetries in (3+1)D topological phases of matter</a>\n
 by Maissam Barkeshli (Maryland) as part of Symmetry Seminar\n\n\nAbstract\
 n(3+1)D topological phases of matter can host interesting classes of non-t
 rivial topological defects of varying codimension\, of which the well-know
 n point charges and flux loops are special cases. The complete algebraic s
 tructure of these defects defines a higher category\, and can be viewed as
  an emergent higher symmetry. This plays an important role both in the cla
 ssification of phases of matter and the possible fault-tolerant logical op
 erations in quantum error correcting codes. In this talk I will discuss so
 me recent progress in our understanding of the properties of invertible de
 fects and higher group symmetries in (3+1)D topological phases of matter. 
 Along the way I will review some progress over the past few years in chara
 cterizing topological phases of matter and their defects in low dimensions
