Abstract
A Floquet representation of the Wannier atomic states was employed for the calculation of Wannier-Stark ladders induced by gravity on atoms in optical lattices. The widths of the Wannier-Stark ladder of resonances were obtained by the dynamics of ultracold atoms in an optical potential. The rate transition to the continuum was obtained by the width of the resonances. A physical model was developed for the Wannier states including the eigenstates of the system in the absence of gravitational field.
