In a recent work, Grossman and Mitas have proposed a strategy to correct ab-initio Molecular Dynamics energies with QMC [62]. This is however different from CEIMC because the nuclear degrees of freedom are still sampled on the basis of DFT forces. Therefore, when applied to metallic hydrogen, that method would have found the same liquid structure as obtained by CPMD-LDA [54].
