我们提出了两种新的修饰电感环陷阱的几何结构，理想的原子干涉或超流性的研究，非常适合在原子芯片架构的利用。该设计允许环半径目前只能通过近衍射限制的光学陷阱，同时保持感应陷阱提供的超平滑磁势。一种几何结构提供了简单的并行实现多个环，而另一种几何结构允许轴向光束分裂的环面适合于整个环原子干涉。
We present two novel dressed inductive ring trap geometries, ideal for atom interferometry or studies of superfluidity and well-suited to utilization in atom chip architectures. The design permits ring radii currently only accessible via near-diffraction-limited optical traps, whilst retaining the ultra-smooth magnetic potential afforded by inductive traps. One geometry offers simple parallel implementation of multiple rings, whereas the other geometry permits axial beam-splitting of the torus suitable for whole-ring atom interferometry.
