Hi
I want to calculate binding energy which defined as the difference between excitation energy and the QP energy. But, I don't know how to find QP energy by yambo
Thank you in advance

Dear Fatima,
binding energy is defined as difference between QP electronic gap and excitation energies. You can calculate it by performing a GW calculation for obtaining the QP gap and a Bethe-Salpeter calculation for the excitation energy. There are tutorials that explain how to calculate both.
