旋转双组分费米子原子气体中泡利顺磁性的振荡
Oscillation of Pauli Paramagnetism in Rotating Two-Component Fermionic Atom Gases
摘要：
通过在均匀磁场中旋转双组分费米子原子气体，构造了一个类似于de Haas-van Alphen效应的物理情形。计算了系统的磁矩，发现由于转动产生的有效磁场的存在，系统的磁矩也表现出关于磁场的振荡行为，但与著名的de Haas-van Alphen效应的振荡完全不同.这种区别是由于在原子气体中，原子的轨道运动只与转动相耦合，而根据原子的电荷中性，对磁矩没有贡献。
英文摘要：
By rotating two-component fermionic atom gases in uniform magnetic field, a similar physical situation with de Haas-van Alphen effect is constructed. We calculate magnetic moment of the system and find that owing to an existence of effective magnetic field coming from the rotation, the magnetic moment also shows the oscillatory behavior about magnetic field, but it is completely different from the famous oscillation of de Haas-van Alphen effect. This distinction is due to that in the atomic gases the orbital motion of atom only couples to rotation and does not contribute to magnetic moment in the light of atomic charge neutrality.
