Loop corrections to scalar quintessence potentials.

Doran, M. and Jaeckel, J. (2002) 'Loop corrections to scalar quintessence potentials.', Physical review D : particles and fields., 66 . p. 43519.


The stability of scalar quintessence potentials under quantum fluctuations is investigated for both uncoupled models and models with a coupling to fermions. We find that uncoupled models are usually stable in the late universe. However, the coupling to fermions is severely restricted. We check whether a graviton induced fermion-quintessence coupling is compatible with this restriction.
