课程描述 DescriptionVertex operator algebras (VOAs) are mathematical objects describing 2d chiral conformal field theory. The representation category of a “strongly rational” VOA is a modular tensor category (which yields a 3d topological quantum field theory), and conjecturally, all modular tensor categories arise from such VOA representations. Conformal blocks are the crucial ingredients in...
AbstractI will describe a certain class of short-range correlated pure states of 2d lattice systems naturally associated with a unitary rational vertex operator algebra. I will argue that such states realize the chiral topological order associated with this vertex algebra. The construction provides a natural way to insert anyons and compute certain topological invariants. It also gives candidat...
