A priori prediction of the cohesive energy of one-dimensional metallic hydrogen
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. 2 figures, 1 table.
