手征Barnett效应引起的涡流磁化
Eddy magnetization from the chiral Barnett effect
摘要：
我们用动力学理论讨论了旋转手征费米子的自旋、角动量和磁矩。我们发现，除了沿旋转轴的手征涡的贡献，有限的圆自旋极化诱导的手征费米子的自旋动量相关，这是取消了轨道角动量的变化。我们指出，由于$g$因子的存在，涡旋磁矩是不为零的，表现出手征巴尼特效应。
英文摘要：
We discuss the spin, the angular momentum, and the magnetic moment of rotating chiral fermions using a kinetic theory. We find that, in addition to the chiral vortical contribution along the rotation axis, finite circular spin polarization is induced by the spin-momentum correlation of chiral fermions, which is canceled by a change in the orbital angular momentum. We point out that the eddy magnetic moment is nonvanishing due to the $g$-factors, exhibiting the chiral Barnett effect.
