Description
In this talk, I will discuss some aspects of the 1-dimensional spin chains that arise in the planar limit of 4d Superconformal theories with a quiver description. These spin chains exhibit various exotic features such as restricted Hilbert spaces and Hamiltonians which are dynamically determined at each site. Correspondingly, understanding their symmetries requires extending standard notions of symmetry based on groups to groupoids and dynamical versions thereof. I will briefly explain these concepts as well as touch upon recent work reformulating these chains in terms of a generalised Temperley-Lieb algebra.
