Revision as of 16:08, 23 March 2021
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
(2) follow the link to Bethe-Salpeter solver: Lanczos-Haydock then return to this tutorial
(3) follow the link to Bethe-Salpeter solver: SLEPC then return to this tutorial
