We report on measurements of resonantly enhanced tunneling of Bose-Einstein condensates loaded into an optical lattice. By controlling the initial conditions of our system we were able to observe resonant tunneling in the ground and the first two excited states of the lattice wells. We also investigated the effect of the intrinsic nonlinearity of the condensate on the tunneling resonances.
我们报告了关于加载到光学晶格中的玻色-爱因斯坦凝聚体的共振增强隧穿的测量结果。通过控制我们系统的初始条件,我们能够在晶格阱的基态以及前两个激发态中观察到共振隧穿。我们还研究了凝聚体的固有非线性对隧穿共振的影响。
