论文摘要
如果原子相互吸引，则可以形成分子。在这里，我们表明原子也能够形成绑定状态，不是由于有吸引力的相互作用而是由于破坏性干扰。如果相互作用的势能随着两个原子之间的距离的变化而变化，则安德森定位会导致形成指数定位的结合状态。尽管自然界中不存在无序的相互作用电位，但我们表明可以通过在实验室中实现Anderson分子的原子和物体之间的原始相互作用潜力的强度来创建它们。
Atoms can form molecules if they attract each other. Here, we show that atoms are also able to form bound states not due to the attractive interaction but because of destructive interference. If the interaction potential changes in a disordered way with a change of the distance between two atoms, Anderson localization can lead to the formation of exponentially localized bound states. While disordered interaction potentials do not exist in nature, we show that they can be created by means of random modulation in time of the strength of the original interaction potential between atoms and objects that we dub Anderson molecules can be realized in the laboratory.
