Exciton Interaction Kernel

Post by Aneesh598 » Thu Aug 10, 2023 3:04 pm

Dear Yambo team,

I was wondering if there is a way to output the exciton interaction kernel so that it is human-readable. I was hoping to calculate the overlap integrals in the direct term. Thanks in advance!

Dear Aneesh,
BSE matrix elements can be extracted using the yambopy utility:

In this thread, you can find instruction on how to extract such elements:
