摘要:

在实验和理论相结合的努力,我们证明了一种新型的偶极系统的超冷玻色子偶极分子与大的磁偶极矩。我们的偶极分子是由强磁性玻色子铒原子样品在弱束缚Feshbach分子态中形成的。我们表明,超冷磁性分子可以携带非常大的偶极矩,我们演示了如何创建和表征它们,以及如何改变它们的方向。最后,我们确认,在准二维几何结构中的分子的弛豫速率可以减少通过使用偶极-偶极相互作用的各向异性,这种减少遵循一个普遍的偶极行为。

英文摘要:

In a combined experimental and theoretical effort, we demonstrate a novel type of dipolar system made of ultracold bosonic dipolar molecules with large magnetic dipole moments. Our dipolar molecules are formed in weakly bound Feshbach molecular states from a sample of strongly magnetic bosonic erbium atoms. We show that the ultracold magnetic molecules can carry very large dipole moments and we demonstrate how to create and characterize them, and how to change their orientation. Finally, we confirm that the relaxation rates of molecules in a quasi-two dimensional geometry can be reduced by using the anisotropy of the dipole-dipole interaction and that this reduction follows a universal dipolar behavior.
