    "abstract": "We discuss a recently demonstrated type of microwave spectroscopy of trapped\nultra-cold atoms known as \"echo spectroscopy\" [M.F. Andersen et. al., Phys.\nRev. Lett., in press (2002)]. Echo spectroscopy can serve as an extremely\nsensitive experimental tool for investigating quantum dynamics of trapped atoms\neven when a large number of states are thermally populated. We show numerical\nresults for the stability of eigenstates of an atom-optics billiard of the\nBunimovich type, and discuss its behavior under different types of\nperturbations. Finally, we propose to use special geometrical constructions to\nmake a dephasing free dipole trap.",
