Abstract

We carry out an ab-initio calculation of the electroń-phonon coupling constant λ for the incommensurate linear chain metal Hg_3-δAsF₆. We find that the intra-chain coupling λ_// is very weak, less than 0.1, while the inter-chain coupling λ_⊥ is very strong, close to 1. This value of λ accounts for the resistivity in the normal state, for the absence of a Peierls transition, and also for bulk superconductivity with a transition temperature of several degrees.
