A PrioriPrediction of the Cohesive Energy of One-Dimensional Metallic Hydrogen

This is the authors' abstract. We don't add key points for this paper.

Ab initio wave functions and properties have been calculated for 14-, 26-, 38-, 50-, and 62-membered rings of hydrogen atoms. The properties converge rather quickly (with respect to the number of atoms in the ring) to those expected for one-dimensional metallic hydrogen. Electron correlation is explicitly considered by way of extensive configuration interaction. The cohesive energy is predicted to be 1.73 ±{} 0.2 eV per hydrogen atom.
