Phys. Rev. D 66, 043519 (2002) [7 pages]Loop corrections to scalar quintessence potentialsReceived 10 May 2002; published 19 August 2002 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. © 2002 The American Physical Society URL:
