LetzElPhC abbreviates to "Lëtzebuerg Electron Phonon Code". "Lëtzebuerg" is the Luxembourgish name for the Luxembourg Country.

LetzElPhC is distributed under the MIT license.

Please refer to the (currently evolving) LetzElPhC documentation for usage.

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

In case of any bugs or other issues, please open a issue.

Any contribtions to the code are always welcomed.

It should be noted that this code computes only electron–phonon matrix elements and does not evaluate any additional physical quantities. If you wish to calculate physical properties using Wannier-based interpolation techniques, you should instead use specialized tools such as EPW, Perturbo, Epiq, or Phoebe.
