我们已经在基于周期性磁化录像带的永磁原子芯片上产生了玻色-爱因斯坦凝聚。我们观察到的膨胀和动力学的冷凝物中的一个微观波导接近表面。原子在该电介质材料附近保持被捕获的寿命显著长于相同厚度的金属表面上方。这些结果说明了微观永磁结构的量子相干制备和操纵冷原子的适用性。
We have produced a Bose-Einstein condensate on a permanent-magnet atom chip based on periodically magnetized videotape. We observe the expansion and dynamics of the condensate in one of the microscopic waveguides close to the surface. The lifetime for atoms to remain trapped near this dielectric material is significantly longer than above a metal surface of the same thickness. These results illustrate the suitability of microscopic permanent-magnet structures for quantum-coherent preparation and manipulation of cold atoms.
