PyDMFT

A python library to work on quantum interacting systems. It is focused for research using the Dynamical Mean Field Theory (DMFT)dmft-rmp

The particular highlight of this library is the gallery of examples for which I have developed the scripts to reproduce known results in this field and also provide with my personal research work, showing how it was done and referencing the publication it appeared. Other examples are just test that resulted in dead ends. Examples exist but not all of them are well documented.

You can access the documentation in (https://titan-c.github.io/pydmft)

If you find problems with it, open an issue or even better a pull request. If you use it cite it.

This library was developed during my Doctoral research stay at the Laboratoire de Physique des solides in Orsay, France.

Installation

This package is python2 and python3 compatible, but let's try go be in the present and use python3 unless you have really ancient dependencies.

I also prefer working in linux systems and thus the instructions are suited for them.

Virtual environment

Although you can install this package system-wide I recommend using a python virtual environment. There are few options, to do this search on the internet to learn more and stay up to day on the current trends. For the moment, and specially for scientific python I use the conda virtual environments.

The next commands for your terminal help you install conda and setup a virtual environment named pydmft with the dependencies for this project.

wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh
chmod +x miniconda.sh
./miniconda.sh -b
export PATH=$HOME/miniconda3/bin:$PATH
conda update --yes --quiet conda
# Install python 3.6 and dependencies in the pydmft virtual environment
conda create --yes --quiet -n pydmft python=3.6 nomkl openblas pip scipy numpy matplotlib sphinx setuptools cython tornado pyzmq h5py joblib pandas numba
source activate testenv
pip install slaveparticles sphinx-gallery mako mpi4py cmocean

Installing the package

This clones the repository and let's you install it on development version. Which means that if you edit the code those changes will affect your installed version. If that is not a behavior you desire change develop for install in the last line.

git clone https://github.com/Titan-C/pydmft.git
cd pydmft
python setup.py develop
