EPW is an open-source F90/MPI code which calculates properties related to the electron-phonon interaction
|
|
using [Density-Functional Perturbation Theory](http://journals.aps.org/rmp/abstract/10.1103/RevModPhys.73.515)
|
|
and [Maximally Localized Wannier Functions](http://journals.aps.org/prb/abstract/10.1103/PhysRevB.56.12847).

The EPW software is only tested and intened to run on Linux (Mac OS might work but not tested).
|
|
|
|
* Download the latest version of [[Quantum-ESPRESSO]](http://www.qe-forge.org/gf/project/q-e/frs/?action=FrsReleaseBrowse&frs_package_id=18).
|
|
|
|
* Unpack and configure Quantum-ESPRESSO
|
|
```bash
|
|
tar -xvf espresso-5.4.0.tar.gz && cd espresso-5.4.0 && ./configure
|
|
```
|
|
|
|
* Compile EPW (this will also compile pwscf, phonon, and wannier90)
|
|
```bash
|
|
make -j 4 pwall
|
|
make -j 4 ph
|
|
make -j 4 epw
|
|
```
