DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IAMP_seminar
 s/184/">Anyons in Quantum Spin Systems: Superselection Sectors and How to 
 Compute Them</a>\nby Alex Bols (ETH Zürich) as part of One world IAMP mat
 hematical physics seminar\n\n\nAbstract\nThe theory of superselection sect
 ors\, first developed in algebraic quantum field theory and more recently 
 adapted to quantum spin systems by Naaijkens and Ogata\, provides a rigoro
 us description of the anyonic excitations hosted by gapped ground states o
 f (2+1)-dimensional quantum systems. After a brief introduction to the gen
 eral framework\, I will sketch how the sector theory can be computed expli
 citly in a class of exactly solvable models.\nThe talk is based on joint w
 ork with Mahdie Hamdan\, Boris Kjær\, Pieter Naaijkens\, and Siddarth Vad
