    "abstract": "We investigate the coherence properties of thermal atoms confined in optical\ndipole traps where the underlying classical dynamics is chaotic. A perturbative\nexpression derived for the coherence of the echo scheme of [Andersen et. al.,\nPhys. Rev. Lett. 90, 023001 (2003)] shows it is a function of the survival\nprobability or fidelity of eigenstates of the motion of the atoms in the trap.\nThe echo coherence and the survival probability display \"system specific\"\nfeatures, even when the underlying classical dynamics is chaotic. In\nparticular, partial revivals in the echo signal and the survival probability\nare found for a small shift of the potential. Next, a \"semi-classical\"\nexpression for the averaged echo signal is presented and used to calculate the\necho signal for atoms in a light sheet wedge billiard. Revivals in the echo\ncoherence are found in this system, indicating they may be a generic feature of\ndipole traps.",
