反磁性和顺磁性混合原子的交感冷却
Sympathetic cooling in a mixture of diamagnetic and paramagnetic atoms
摘要：
我们将镱的双色光偶极阱与铷的Ioffe-Pritchard型磁阱相结合，在实验上实现了超冷顺磁性铷原子和反磁性镱原子的混合阱。在这个混合阱中，通过与铷的弹性碰撞实现了五种不同的镱同位素的共振冷却。观察到镱同位素的质量上的种间碰撞截面的强烈依赖性。
英文摘要：
We have experimentally realized a hybrid trap for ultracold paramagnetic rubidium and diamagnetic ytterbium atoms by combining a bichromatic optical dipole trap for ytterbium with a Ioffe-Pritchard-type magnetic trap for rubidium. In this hybrid trap, sympathetic cooling of five different ytterbium isotopes through elastic collisions with rubidium was achieved. A strong dependence of the interspecies collisional cross section on the mass of the ytterbium isotope was observed.
