Double grid in BSE

Post by shenchenhai » Sun Mar 10, 2019 5:34 am

Dear developers,
Double grid method is a very good technology for the calculation of optical properties in Yambo. I've interpolated the GW eigen energy through wannier90, but I don't know how to use the QP energy obtained by interpolation to do the double grid calculation in the next BSE calculation. Could you give me some hints? Thank you very much.

Yours sincerely,

Dear Shen

there is an option in ypp -b to read the BXSF file generated by Wannier90,
check if it works, otherwise we can fix it
