DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/44/">
 Fusion surface models: 2+1d lattice models from fusion 2-categories</a>\nb
 y Kansei Inamura (Tokyo) as part of Symmetry Seminar\n\n\nAbstract\nWe wil
 l discuss a systematic way to construct (2+1)-dimensional lattice models w
 ith finite generalized symmetries described by fusion 2-categories. These 
 models are 2+1d analogues of the 1+1d anyon chain models and are dubbed fu
 sion surface models. We will also see that our models naturally arise from
  4d topological field theories put on a slab. Examples of fusion 2-categor
 ies include modular tensor 1-categories that describe the symmetries gener
 ated by anyons. Thus\, the fusion surface models with such symmetries may 
 provide natural candidates for chiral topological phases on the lattice.\n
