论文摘要
近场，围绕悬浮纳米球的径向对称光电位可用于交感冷却，并创建类似于大分子的结合纳米层原子系统。我们证明，由单个蓝色的蓝色场产生的远距离，类似库仑的电势将碰撞的横截面增加了八个数量级，从而可以使用冷原子对捕获的纳米球的快速交感神经冷却至微蛋白原温度。通过使用两个光场创建排斥和有吸引力的电势的组合，我们证明了一个冷原子可以与纳米球结合，从而形成一个新的浮动杂种量子系统，适合于探索具有质量质量的量子力学。
Near-field, radially symmetric optical potentials centred around a levitated nanosphere can be used for sympathetic cooling and for creating a bound nanosphere-atom system analogous to a large molecule. We demonstrate that the long range, Coulomb-like potential produced by a single blue detuned field increases the collisional cross-section by eight orders of magnitude, allowing fast sympathetic cooling of a trapped nanosphere to microKelvin temperatures using cold atoms. By using two optical fields to create a combination of repulsive and attractive potentials, we demonstrate that a cold atom can be bound to a nanosphere creating a new levitated hybrid quantum system suitable for exploring quantum mechanics with massive particles.
