lambda_weight is a program to calculate electron-phonon couplings using weighted average method. For details, see
T. Koretsune and R. Arita, Computer Physics Communications 220 239-242 (2017) ( arxiv:1610.09441 )
Currently, the program is based on the quantum-ESPRESSO v6.0.
1. Download or clone the github repository, e.g.
> git clone https://github.com/elph-dev/lambda_weight
2. Apply a patch to the qe-6.0/PHonon/PH directory.
> cd PATH/TO/QEDIR/qe-6.0/PHonon
> cp -a PH PHelph
> cd PHelph
> patch -p1 < LAMBDA_WEIGHT_DIR/qe-6.0/lambda_weight.patch
3. Compile
> cd PHelph
> make ( lambda_weight.x )
You can find an example in qe-6.0/examples/Nb. See README in this directory for more details.
