Towards the solution of the many-electron problem in real materials: equation of state of the hydrogen chain with state-of-the-art many-body methods

ORAL

Abstract

We present numerical results for the equation of state of an infinite chain of hydrogen atoms. A
variety of modern many-body methods are employed, with exhaustive cross-checks and
validation. Approaches for reaching the continuous space limit and the thermodynamic limit
are investigated, proposed, and tested. The detailed comparisons provide a benchmark for
assessing the current state of the art in many-body computation, and for the development of
new methods. The ground-state energy per atom in the linear chain is accurately determined
versus bondlength, with a confidence bound given on all uncertainties [1].
