Fig. 3: Dynamical and superconducting properties of the representative 2 × 2 × 2 system.
From: Molecular hydrogen in the N-doped LuH3 system as a possible path to superconductivity
Top: phonon spectrum density of states of LuH2.875N0.125 in the presence of H2 molecules. The character of eigenvalues is highlighted (in red the total H character, in green the molecular contribution, in cyan the nitrogen one, and in yellow the total Lu character). Bottom: the evaluated Eliashberg function (α2F(ω)) and the electron phonon coupling constant (λ(ω) in orange).
