# Sudden singularities survive massive quantum particle production

@article{Barrow2011SuddenSS, title={Sudden singularities survive massive quantum particle production}, author={J. Barrow and A. B. Batista and G. Dito and J. Fabris and M. Houndjo}, journal={Physical Review D}, year={2011}, volume={84}, pages={123518} }

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.
