Fixed-point tensor network construction and generalised symmetry for conformal field theory

Prof. Zhengcheng Gu from the Chinese University of Hong Kong gives an analytical construction of the fixed point tensors of a 2D rational CFT and provides a concrete example by using several models to compute the scaling dimensions explicitly. He shows that the construction of the fixed point tensors is closely related to a strange correlator, where the holographic picture and generalised symmetries naturally emerge.
