1110.1321 (J. D. Barrow et al.)

Sudden singularities survive massive quantum particle production    [PDF]

J. D. Barrow, A. B. Batista, G. Dito, J. C. Fabris, S. Houndjo
We solve the Klein-Gordon equation for a massive, non-minimally coupled scalar field, with a conformal coupling, undergoing cosmological evolution from a radiation-dominated phase to a future sudden singularity. We show that, after regularisation, the energy of the created particles is zero and the back-reaction from quantum effects does not change the evolution of the universe near the future singularity and cannot prevent the finite-time sudden singularity.
