DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMU-TP/29/">
 Higher-form and higher-group symmetry in mixed superfluids</a>\nby Tomas B
 rauner (Stavanger University) as part of Carnegie Mellon theoretical physi
 cs\n\n\nAbstract\nHigher-form symmetries are symmetries that act on extend
 ed objects. I will give a brief introduction to this concept and show how 
 higher-form symmetries naturally emerge as a consequence of spontaneous br
 eaking of ordinary (0-form) symmetries. They can therefore be expected to 
 be present in superfluids and generalizations thereof. Furthermore\, when 
 two or more different types of superfluids are mixed\, a more general symm
 etry structure appears\, usually referred to as a higher group. The presen
 ce of this mathematical structure reflects the interplay of topological de
 fects of the various superfluid components.\n
