Introduction
************
A library for running the Wolff algorithm on arbitrary systems in arbitrary
fields. A "spin state" and "spin symmetry transformation" type must be supplied
to define a system, along with a spin-spin coupling, a spin-field coupling,
and a generator of transformations of rank two. The library then supplies the
tools to run Wolff cluster-flip Monte Carlo on the resulting system, with
arbitrary measurements taken along the way.
A detailed description of the algorithm and its requirements can be found at https://arxiv.org/abs/1805.04019.
Getting Wolff
=============
This source for this library is available at https://git.kent-dobias.com/wolff/.
Installation
============
The only dependencies are a modern C++ compiler, cmake, and the standard libraries. With those at hand, the Wolff library and the provided examples can be built and installed using
.. code-block:: bash
git clone https://git.kent-dobias.com/wolff/
mkdir wolff/build
cd wolff/build
cmake ..
make install
Custom install paths and compiler optimizations can be passed to cmake in the standard ways.
License
=======
Wolff is licensed under the MIT license, a copy of which is included with the source code. The terms can be found here: https://spdx.org/licenses/MIT.html.
