Electron-hole exchange matrix elements

Anything regarding the post-processing utility (e.g. excitonic wavefunction analysis) is dealt with in this forum.

Electron-hole exchange matrix elements

Post by Danslie » Thu Jan 09, 2025 3:21 am

Dear developers,
Is it possible to read the electron-hole exchange matrix elements after BSE calculations?

Looking forward to your response.

Best wishes

Dear Dan,

you can perform a calculation including electron-hole exchange term only in the kernel and then read the matrix elements using the yambopy (see viewtopic.php?p=12305#p12305).

Best,
Daniele
