Description
In this talk, I will discuss the deep connection between tensor network renormalization method and renormalization group concept. I will explain how to use this connection to extract the critical point and critical exponents. After that I will further extend the connection to conformal field theory. I will explain how to extract conformal data, including central charge, scaling dimension, conformal spin, operator product expansion coefficients. I will use 2D Ising model and 3-state clock model as examples. Finally, I will discuss the generalization to 3D models and to complex CFT.
