Query: Tensor renormalization group study of the 2d O(3) model   We present our progress on a study of the $O(3)$ model in two-dimensions
using the Tensor Renormalization Group method. We first construct the theory in
terms of tensors, and show how to construct $n$-point correlation functions. We
then give results for thermodynamic quantities at finite and infinite volume,
as well as 2-point correlation function data. We discuss some of the advantages
and challenges of tensor renormalization and future directions in which to
work.
