我们研究了弱耦合极限下直流-交流电场驱动的双布洛赫带的紧束缚模型。布洛赫能带之间的拉比振荡在共振条件下被识别，其中准能带和分数万尼尔-斯塔克阶梯都被揭示。讨论了观察预测效果的实验条件。
We investigate a tight-binding model of double Bloch bands driven by dc-ac electric fields in the weak-coupling limit. Rabi oscillations between the Bloch bands are identified under resonant conditions, in which the quasienergy bands and fractional Wannier-Stark ladders are all revealed. Experimental conditions for the observation of the predicted effects are discussed.
