Reduced Contraction Costs of Corner-Transfer Methods for PEPS
Wangwei Lan, Glen Evenbly
We propose a pair of approximations that allows the leading order computational cost of contracting an infinite projected entangled-pair state (iPEPS) to be reduced from $\mathcal{…

Tensor Renormalization Group Centered About a Core Tensor
Wangwei Lan, Glen Evenbly
We propose a modified form of a tensor renormalization group algorithm for evaluating partition functions of classical statistical mechanical models on 2D lattices. This algorithm…
