Testing the Shukla-Eliasson attractive force between protons in dense hydrogen — •Michael Bonitz, Eckhard Pehlke, and Tim Schoof — Institut für Theoretische Physik und Astrophysik, CAU Kiel, Leibnizstr. 15

In a recent letter [1] the discovery of a new attractive force between protons in a dense hydrogen plasma was reported that - according to the authors - would be responsible for the formation of molecules and of a proton lattice. Here we show, based on ab initio density functional calculations and general considerations, that these predictions have no factual basis and are caused by using linearized quantum hydrodynamics beyond the limits of its applicability [2].
