论文摘要
在距表面距离距离处原子的量子控制将打开量子光学元件的新范式，并为研究近表面物理学提供新颖的工具。在这里，我们研究了与热光学纳米纤维表面薄弱结合的原子的运动状态。从理论上讲，我们证明，尽管纳米纤维的优化机械性能，尽管声子诱导的反应性，但这些状态被量化。我们进一步表明，有可能通过其他纳米纤维引导的光场影响其性质，并建议杂化荧光光谱以探测量化原子运动的光谱。将原子的光学控制扩展到较小的原子表面分离可以为量子通信创造机会，并激发表面物理，量子光学元件和冷原子物理学的收敛性。
Quantum control of atoms at ultrashort distances from surfaces would open a new paradigm in quantum optics and offer a novel tool for the investigation of near-surface physics. Here, we investigate the motional states of atoms that are bound weakly to the surface of a hot optical nanofiber. We theoretically demonstrate that with optimized mechanical properties of the nanofiber these states are quantized despite phonon-induced decoherence. We further show that it is possible to influence their properties with additional nanofiber-guided light fields and suggest heterodyne fluorescence spectroscopy to probe the spectrum of the quantized atomic motion. Extending the optical control of atoms to smaller atom-surface separations could create opportunities for quantum communication and instigate the convergence of surface physics, quantum optics, and the physics of cold atoms.
