    "abstract": "In this paper I study the dynamics of a two-level atom interacting with a\nstanding wave field. When the atom is subjected to a weak linear force, the\nproblem can be turned into a time dependent one, and the evolution is\nunderstood from the band structure of the spectrum. The presence of level\ncrossings in the spectrum gives rise to Bloch oscillations of the atomic\nmotion. Here I investigate the effects of the atom-field detuning parameter. A\nvariety of different level crossings are obtained by changing the magnitude of\nthe detuning, and the behaviour of the atomic motion is strongly affected due\nto this. I also consider the situation in which the detuning is oscillating in\ntime and its impact on the atomic motion. Wave packet simulations of the full\nproblem are treated numerically and the results are compared with analytical\nsolutions given by the standard Landau-Zener and the three-level Landau-Zener\nmodels.",
