    "abstract": "The time evolution of a two-level atom which is simultaneously exposed to the\nfield of a running laser wave and a homogeneous gravitational field is studied.\nThe result of the coupled dynamics of internal transitions and center-of-mass\nmotion is worked out exactly. Neglecting spontaneous emission and performing\nthe rotating wave approximation we derive the complete time evolution operator\nin an algebraical way by using commutation relations. The result is discussed\nwith respect to the physical implications. In particular the long time and\nshort time behaviour is physically analyzed in detail. The breakdown of the\nMagnus perturbation expansion is shown.",
