Computing the renormalization group flow of two-dimensional ϕ^{4} theory with tensor networks
We study the renormalization group flow of ϕ^{4} theory in two dimensions. Regularizing space into a fine-grained lattice and discretizing the scalar field in a controlled way, we rewrite the partition function of the theory as a tensor network. Combining local truncations and a standard coarse-grai...
