Institut fu¨r Theoretische Physik, Universit¨at Innsbruck, Technikerstr. 25, A-6020 Innsbruck, Austria(February 1, 2008; submitted to Phys. Rev. A)We study the zero temperature dynamics of Bose-Einsteincondensates in driven high-quality optical cavities in the limitof large atom-field detuning. We calculate the stationaryground state and the spectrum of coupled atom and fieldmode excitations for standing wave cavities as well as fortravelling wave cavities. Finite cavity response times leadto damping or controlled amplification of these excitations.Analytic solutions in the Lamb-Dicke expansion are in goodagreement with numerical results for the full problem andshow that oscillation frequencies and the corresponding damp-ing rates are qualitatively different for the two cases.PACS number(s): 03.75.Fi, 05.30.Jp, 32.80.Pj, 42.50.VkI.
