In a paper on arXiv, Bonitz et al (2012 arXiv:1205.4922v1 [physics.plasm-ph]) (hereafter referred to as BPS) erroneously attributed the qualitative discrepancy between their density functional theory (DFT) simulation results with the analytical discovery of the Shukla–Eliasson (SE) attractive force which brings ions closer to the failure of the linearized quantum hydrodynamic theory. In this paper, we describe the underlying physics of the novel SE attractive force and its validity, as well as discuss some of the key features of the well-established quantum hydrodynamic theory and working mechanisms for DFT simulations, in addition to giving some critical notes on the falsified and misleading conclusions presented by BPS in their dubious paper. Furthermore, we also present a mass-density value for possible 4He metallic plasma lattice formation under the SE force.
