Intro

EPWpy is an open-source python code which wraps EPW code for automated calculations. EPWpy provides python objects with methods that can be used to automate DFT+EPW calculations using Quantum Espresso and EPW.EPWpy also provides a series of visualization utilities for plotting various quantities. EPW is a F90/MPI code which calculates properties related to the electron-phonon interaction using Density-Functional Perturbation Theory and Maximally Localized Wannier Functions. The name is derived from the words "Electron-phonon Wannier" which refer to the Wannier-Fourier interpolation method employed by the code. The development and co-ordination of EPWpy is led by Sabyasachi Tiwari and Feliciano Giustino.
