Intro

EPW is an open-source 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 of EPW is led by Sabyasachi Tiwari, Samuel Poncé, Emmanouil Kioupakis, Roxana Margine, and Feliciano Giustino.
