The recent paper by Tawfik et al. entitled with "Perturbative Instability of Cosmology from Quantum Potential" https://journals.aps.org/prd/abstract/10.1103/PhysRevD.93.063526 shows that Ali and Das, "Cosmology from quantum potential," http://arxiv.org/abs/1404.3093 which was commented in...
A good year ago, quantum corrections have been proposed to the very early Universe. It was concluded that these quantum corrections contain a precise estimation for the cosmological constant and the so-called radiation term. The authors even have interpreted the latter as evading the big-bang...
I believe that one should first examine various stability conditions. This was done for instance in a recent PRD paper https://journals.aps.org/prd/abstract/10.1103/PhysRevD.93.063526. Accordingly the world model with such corrections is simply unstable.
