报告摘要:
In recent years, the concepts and techniques of topological field theory have received growing attention in the field of high energy physics, such as symTFT. In this talk, I will show that the path integral of conformal field theories in D dimensions (CFTD) can be constructed by solving for eigenstates of a renormalization group (RG) operator following from the Turaev-Viro formulation of a topological quantum field theory in D+1 dimensions (TQFTD+1), explicitly realizing the holographic relation between a symmetric theory and a TQFT. Generically, exact eigenstates corresponding to symmetric TQFTD follow from Frobenius algebra in TQFTD+1. For D= 2, we construct eigenstates that produce 2D rational CFT path integrals exactly, which curiously connect a continuous-field theoretic path integral with the Turaev-Viro state sum. We also devise and illustrate numerical methods for D= 2, 3 to search for CFTD as phase transition points between symmetric TQFTD.
