Tensor Renormalization Group at Low Temperatures
Slava Rychkov (IHES)
Abstract: Tensor RG is a real-space approach to renormalization in lattice models. It shows impressive numerical results, but its rigorous theory is still in its infancy. I will start by reminding the basics of Tensor RG, and what makes it potentially more powerful than Wilson-Kadanoff approach. I will then explain how Tensor RG can be used to understand the Ising model in nonzero magnetic field at low temperatures. This gives an alternative to the Pirogov-Sinai theory and to the renormalization group methods in the contour representation from the 1980’s. Joint work with Tom Kennedy, to appear soon.
