The recently developed tensor renormalization-group (TRG) method provides a highly precise technique for deriving thermodynamic and critical properties of lattice Hamiltonians. The TRG is a local coarse-graining transformation, with the elements of the tensor at each lattice site playing the part of the interactions that undergo the renormalization-group flows. These tensor flows are directly related to the phase diagram structure of the infinite system, with each phase flowing to a distinct…

Critical correlations of Ising and Yang-Lee critical points from Tensor RG
We examine feasibility of accurate estimations of universal critical data using tensor renormalization group (TRG) algorithm introduced by Levin and Nave 1 . Specifically, we compute critical
Using a recently proposed new renormalization group method (tensor renormalization group), we analyze the Ising model on the two-dimensional square lattice. For the lowest-order approximation with
Scaling dimensions from linearized tensor renormalization group transformations
We show a way to analyze a renormalization group (RG) fixed point in tensor space: write down the tensor RG equation, linearize it around a fixed-point tensor, and diagonalize the resulting

We study the phase diagram of ultra-cold bosonic polar molecules loaded on a two-dimensional optical lattice of hexagonal symmetry controlled by external electric and microwave fields. Following a

We examine in detail the accuracy, efficiency and implementation issues that arise when a simplified code structure is employed to evaluate the partition function of the two-dimensional square Ising


Variational approximations for renormalization group transformations
Approximate recursion relations which give upper and lower bounds on the free energy are described. Optimal calculations of the free energy can then be obtained by treating parameters within the

Tensor renormalization group approach to two-dimensional classical lattice models.
A simple real space renormalization group technique for two-dimensional classical lattice models that is fundamentally based on the theory of quantum entanglement is described and demonstrated by computing the magnetization of the triangular lattice Ising model.
Renormalization group solution of the one−dimensional Ising model
A renormalization group approach is applied to the one−dimensional Ising model to obtain a rapidly convergent infinite series expansion for the free energy. This series can be summed and yields the

Classical simulation of quantum many-body systems with a tree tensor network
We show how to efficiently simulate a quantum many-body system with tree structure when its entanglement (Schmidt number) is small for any bipartite split along an edge of the tree. As an
