variPEPS -- Versatile tensor network library for variational ground state simulations in two spatial dimensions.
variPEPS is the Python variant of the tensor network library developed for variational ground state simulations in two spatial dimensions applying gradient optimization using automatic differentation.
For a detailed report on the method, please see our publications listed at the end of this readme.
Installation
Installation using pip
The current version of the variPEPS Python package is available on PyPI. It can be easily installed by using the Python package manager pip:
$ python3 -m pip install variPEPS
Usage
For detailed information how to use the package we want to point out to the documentation of the project.
