Description

Probability and analysis informal seminar

Tensor networks are a recent cool addition to physicist’s toolkit used to study renormalization of lattice models. However the mathematical theory of tensor network renormalization group (TNRG) is still in its infancy. I will aim to transmit my excitement about the tensor networks. Rough plan:
1. Wilson’s conjecture about renormalization group fixed points describing criticality - can we prove it?
2. Why are tensor networks better than other approaches to renormalization (e.g. spin blocking).
3. Numerical algorithms for TNRG - what do people see numerically?
4. Discrete scaling operator
5. A few mathematically rigorous results about TNRG
6. Open problems
