摘要:

我们在低温环境下仅用超导导线在原子芯片上制备了玻色-爱因斯坦凝聚体(BEC)。我们在100 nK的温度下观察到10^4个原子的凝聚开始。这一结果为研究BEC与超导表面相互作用中的原子损耗和退相干开辟了道路。在小而致密的原子样品中,长寿命里德伯原子的偶极阻塞研究正在进行中。

英文摘要:

We have produced a Bose-Einstein condensate (BEC) on an atom chip using only superconducting wires in a cryogenic environment. We observe the onset of condensation for 10^4 atoms at a temperature of 100 nK. This result opens the way for studies of atom losses and decoherence in a BEC interacting with a superconducting surface. Studies of dipole-blockade with long-lived Rydberg atoms in a small and dense atomic sample are underway.
