原子的类布洛赫量子多重反射

Bloch-Like Quantum Multiple Reflections of Atoms

Luis Santos, Luis Roso

摘要:

我们表明,在一定的情况下,原子可以遵循振荡运动的周期性激光轮廓与高斯包络。这些振荡可以很好地解释,通过使用能量禁戒空间区域的模型。与Bloch振荡的异同进行了讨论。我们证明了这种效应不仅存在于排斥势,也存在于吸引势,即量子多重反射也是可能的。

英文摘要:

We show that under certain circumstances an atom can follow an oscillatory motion in a periodic laser profile with a Gaussian envelope. These oscillations can be well explained by using a model of energetically forbidden spatial regions. The similarities and differences with Bloch oscillations are discussed. We demonstrate that the effect exists not only for repulsive but also for attractive potentials, i.e. quantum multiple reflections are also possible.
