摘要：

The paper studies the effect of a weak periodic driving on metastable Wannier-Stark states. The decay rate of the ground Wannier-Stark states as a continuous function of the driving frequency is calculated numerically. The theoretical results are compared with the experimental data of Wilkinson et nl. [Phys. Rev. Lett. 76, 4512 (1996)] obtained for cold sodium atoms in an accelerated optical lattice.
