Variants of thick-restart Lanczos for the Bethe-Salpeter eigenvalue problem

Fernando Alvarruiz, Blanca Mellado-Pinto, Jose E. Roman

The paper proposes three structure‑preserving Lanczos eigensolver variants with a thick‑restart scheme for the definite non‑Hermitian Bethe‑Salpeter eigenvalue problem, enabling ef…

The WEST code for large-scale excited-state materials simulations

Victor Wen-zhe Yu, Siyuan Chen, Yu Jin +5

The paper introduces WEST, an open‑source plane‑wave pseudopotential code that enables large‑scale excited‑state simulations of materials using GW, Bethe‑Salpeter, and TDDFT method…
