论文摘要
从理论上讲，我们讨论了冷原子的一维链的光学结合，横向泵闪闪发光，其中颗粒自组织到接近光学波长的距离。随着粒子数量的增加，随着所有原子的贡献构建累加，捕获势会增加对数。由于原子之间的光子相互交换，我们确定了一种合作的冷却机制，这可以超过足够长的链的自发发射。令人惊讶的是，冷却非常接近共振。因此，这种特殊的冷却机制为低维冷原子系统的合作物理学提供了新的见解。
We discuss theoretically the optical binding of one-dimensional chains of cold atoms shone by a transverse pump, where particles self-organize to a distance close to an optical wavelength. As the number of particles is increased, the trapping potential increases logarithmically as the contributions from all atoms add up constructively. We identify a cooperative cooling mechanism, due to the mutual exchange of photons between atoms, which can beat the spontaneous emission for chains that are long enough. Surprisingly, the cooling is optimal very close to the resonance. This peculiar cooling mechanism thus gives new insights into the cooperative physics of low-dimensional cold atom systems.
