Please read docs/main.pdf for installing and usage. A simple example can be found in examples/qe/silicon folder

This code is currently under development. please use at your own risk.

In case of any bugs or other issues, please open a gitlab issue at https://gitlab.com/lumen-code/LetzElPhC

Any contribtions to the code are always welcomed. Thank you very much incase you are willing to contribute.

It should be noted that this code does not compute any other quantities apart from electron-phonon matrix elements. In case if you like to compute physical properties due to electron-phonon coupling—such as mobilities, etc, one should prefer other tools such as the EPW code.
