Post subject:  Separate converging of long- and short-range parts of matrix

Dear all,

The EPW has a feature of using different meshes for long- and short-range parts of
the electron-phonon matrix, but is it possible to use this feature
for solving iterative BTE? What the input in this case should be?
Will be grateful for reference to any example.

Best wishes,
Petr

Dear Petr,

This feature is not available for the IBTE.

In practice I found it was not really necessary to split them and converge could be achieved without doing the splitting.

Best wishes,
Samuel

Dear Samuel,

Thank you for your answer. I will try without splitting, though running the short-range part on the same mesh as the long-range one scares me a bit.

Best wishes,
Petr
