EPW (Electron-Phonon Wannier)

  • Openness:3 ★★★
  • Document quality:3 ★★★

EPW (Electron-Phonon Wannier) is software for first-principles calculations of electron-phonon interactions. It utilizes Wannier functions to efficiently interpolate electronic and phononic states, enabling high-precision analysis of electron-phonon coupling and superconducting properties. EPW operates as an extension module of Quantum ESPRESSO (QE), using the results of electronic structure and phonon calculations as input.
