TeneT.jl

CI codecov

This is a Julia package for the Variational Uniform Matrix product states(VUMPS) to contract infinite two-dimension square lattice tensor network.

In this package we implemented the VUMPS algorithms including the following:

  • Complex number forward and backward propagation
  • NixNj Big Unit Cell
  • U1-symmmetry and Z2-symmmetry

This package a updated version of the original ADVUMPS.jl package, so for more easily to learn and use, we recommend you to use ADVUMPS.jl package.

install

> git clone https://github.com/XingyuZhang2018/TeneT.jl

move to the file and run julia REPL, press ] into Pkg REPL

(@v1.7) pkg> activate .
Activating environment at `..\TeneT\Project.toml`

(TeneT) pkg> instantiate

To get back to the Julia REPL, press backspace or ctrl+C. Then Precompile TeneT

Examples

2D Classical Ising Model

A simple example is presentated in ./example/ising.jl to constructing the tensor for the tensor network representation of the 2d classical Ising Model.

julia> include("./example/ising.jl")

You can modify Ni and Nj to change the Unit cell size and atype Array or CuArray to change computation type.
