Creating atom-number states around tapered optical fibres by loading from an optical lattice
摘要：
我们从理论上描述了一种装置，其中锥形光学纳米纤维被引入到冷原子的光晶格势中。首先，我们考虑的晶格势的几何形状的干扰，由于散射的晶格激光器从介电纤维表面，并表明，由此产生的扭曲晶格可以最小化，通过放置在适当的位置在晶格中的纤维。然后，我们计算的修改的本地潜力，可实现通过传输非共振光通过光纤。这种技术的可用性具有确定性地创建和解决锥形纳米纤维的倏逝场中的原子的小的明确定义的样品的潜力。
英文摘要：
We describe theoretically a setup in which a tapered optical nanofibre is introduced into an optical lattice potential for cold atoms. Firstly, we consider the disturbance to the geometry of the lattice potential due to scattering of the lattice lasers from the dielectric fibre surface and show that the resulting distortion to the lattice can be minimized by placing the fibre at an appropriate position in the lattice. We then calculate the modifications of the local potentials that are achievable by transmitting off-resonant light through the fibre. The availability of such a technique holds the potential to deterministically create and address small well-defined samples of atoms in the evanescent field of the tapered nanofibre.
