Comment on "On Novel attractive forces between ions in quantum plasmas   -- failure of linearized quantum hydrodynamics"
  In a recent paper Bonitz, Pehlke and Schoof [1], hereafter referred to as BPS, have raised some points against the newly found Shukla-Eliasson attractive potential [2,3], hereafter refererred to as SEAP, around a stationary test charge in a quantum plasma [2,3]. Our objective here is to discuss the inappropriateness of BPS reasoning concerning the applicability of the linearized quantum hydrodynamic theory, as well as to point out the shortcomings in BSP's arguments and to suggest for rescuing the BSP's density functional theory and simulations which have failed to produce results that correctly match with that of Shukla and Eliasson [2,3].
