Work in progress (please come back after 04/04/2021)

Three main solvers are available in Yambo:

(1) diagonalization of the full Hamiltonian (diagonalization solver)

(2) subspace iterative | Lanczos algorithm which by-pass diagonalization with the Haydock approach[1] (Lanczos-Haydock solver)

(3) SLEPC (to be completed)

For:

(1), you should've already carry out the Bethe-Salpeter solver: diagonalization return to this tutorial

(2) follow the link to Bethe-Salpeter solver: Lanczos-Haydock

(3) follow the link to Bethe-Salpeter solver: SLEPC
