| Outline of Final Research Achievements |
The aim of this research was to construct a nano-lattice in which ultracold atoms are located with the separation of nanometers using a near-field light around a nano-scale structure. First, we calculated the electromagnetic field distribution around a structure illuminated by a plane wave via FDTD method. In particular, we found that a large electric field gradient emerges for the structure with the size less than 20 nm and higher order atom-light interaction can not be neglected. Second, we successfully transferred cold atoms trapped in a near-infrared laser to the region close to a glass cell surface by moving the focus position of the trap beam with a high-precision stage. This technique allows us to prepare cold atoms in the very vicinity of the structure where an near-field exists.
