论文摘要
我们已经分析地探索了3-D自旋偏振的理想诱饵的理想的费米气体的人工磁性，其电气中性颗粒暴露于均匀的合成磁场上。尽管自旋的极化对于将电气陷阱捕获电气中性原子是必需的，但是对于自旋极化的费米系统，不能研究Pauli Promagnetism。但是，可以研究这种系统的Landau Diamagnetism和De Haas-Van Alphen效应。我们已经在一个温度以及在热力学极限下的所有温度以及所有可能的合成磁场的大小上统一了人工兰道diamagnetism和人造de haas-van alphen效应。我们的预测在当今的实验设置中可以测试磁陷阱中的超低效率原子。
We have analytically explored the artificial magnetism for a 3-D spin-polarized harmonically trapped ideal Fermi gas of electrically neutral particles exposed to a uniform synthetic magnetic field. Though polarization of the spin is necessary for trapping electrically neutral atoms in a magneto-optical trap, Pauli paramagnetism can not be studied for the spin-polarized Fermi system. However, it is possible to study Landau diamagnetism and de Haas-van Alphen effect for such a system. We have unified the artificial Landau diamagnetism and the artificial de Haas-van Alphen effect in a single framework for all temperatures as well as for all possible magnitudes of the synthetic magnetic field in the thermodynamic limit. Our prediction is testable in the present-day experimental setup for ultracold fermionic atoms in magneto-optical trap.
