two-particle Green's function to BSE eigenvalue problem

Post by Longjun Xiang » 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.

Dear Longjun,
you can have a look at the Chapter. 3 of the Stefan Albrecht PhD thesis available here.

Or Appendix B in:
Onida, Riening, Rubio REVIEWS OF MODERN PHYSICS, VOLUME 74, APRIL 2002

Best,
