two-particle Green's function to BSE eigenvalue problem
Posted: Thu Nov 26, 2020 3:22 am
Dear developers:
The absorption spectrum with the consideration of electron-hole interaction is obtained by calculating the two-particle Green's function, which satisfies the corresponding Dyson equation. Finally, the Dyson equation for the two-particle Green's function is mapped into the BSE eigenvalue problem, is there any tutorial/slides/notes to talk about the derivation details about this mapping?
Many thanks in advance.
