简谐势阱中量子简并异质玻色-费米混合物的输运
Transport of a quantum degenerate heteronuclear Bose-Fermi mixture in a harmonic trap
摘要：
本文研究了玻色子87 Rb和费米子40 K混合量子简并气体在改进的QUIC阱中的输运。将样品在6 mm的距离上运输到QUIC阱的反亥姆霍兹线圈的几何中心。这种传输机制是通过对QUIC阱进行小的修改来实现的，并且没有损耗和加热。它允许使用QUIC阱的所有实验使用可以在QUIC阱的中心产生的高度均匀的磁场，并改善对原子的光学访问，例如，用于光晶格的实验。这种机制可以级联以覆盖具有量子简并样本的应用的甚至更大的距离。
英文摘要：
We report on the transport of mixed quantum degenerate gases of bosonic 87Rb and fermionic 40K in a harmonic potential provided by a modified QUIC trap. The samples are transported over a distance of 6 mm to the geometric center of the anti-Helmholtz coils of the QUIC trap. This transport mechanism was implemented by a small modification of the QUIC trap and is free of losses and heating. It allows all experiments using QUIC traps to use the highly homogeneous magnetic fields that can be created in the center of a QUIC trap and improves the optical access to the atoms, e.g., for experiments with optical lattices. This mechanism may be cascaded to cover even larger distances for applications with quantum degenerate samples.
