利用表面生长的碳纳米管捕获冷原子
Trapping cold atoms using surface-grown carbon nanotubes
摘要：
我们提出了一个可行性研究加载冷原子云到磁陷阱所产生的单壁碳纳米管直接生长到电介质表面。我们表明，原子可以捕获实验可持续的纳米管电流，产生被困云的密度和寿命是足够的，使简单的成像方法检测。这为一种新型的导体在原子芯片中的应用开辟了道路，使原子能够在亚微米距离上被捕获，这对基础研究和技术应用都有影响。
英文摘要：
We present a feasibility study for loading cold atomic clouds into magnetic traps created by single-wall carbon nanotubes grown directly onto dielectric surfaces. We show that atoms may be captured for experimentally sustainable nanotube currents, generating trapped clouds whose densities and lifetimes are sufficient to enable detection by simple imaging methods. This opens the way for a novel type of conductor to be used in atomchips, enabling atom trapping at sub-micron distances, with implications for both fundamental studies and for technological applications.
