手征等离子体中的磁共振:手征双子

Magnetic monopole in a chiral plasma: chiral dyon

Michael Lublinsky, Jared Reiten, Andrey V. Sadofyev

摘要:

将磁性粒子放入轴向密度不为零的电中性手征等离子体中,会导致物质的电极化的强度。由手征磁效应产生的电流通过电荷扩散和欧姆耗散来平衡,这产生非平凡的电荷分布。反过来,由于手性分离效应,后者诱导手性沿着磁性体的磁场分离。我们发现这样一个系统的定态,消失的总电流和稳定的轴向电流平衡的手征异常。在这种溶液中,电子被一个与物质的平均手征密度成正比的电荷“修饰”--形成一个手征双子。一方面手征效应和另一方面重离子磁场的存在之间的相互作用可能会影响早期宇宙中重离子密度的演化,有助于重子生成的过程,也可以用于使用手征材料检测残余单极子。

英文摘要:

The placement of a magnetic monopole into an electrically-neutral chiral plasma with a non-zero axial density results in an electric polarization of the matter. The electric current produced by the chiral magnetic effect is balanced by charge diffusion and Ohmic dissipation, which generates a non-trivial charge distribution. In turn, the latter induces a separation of chiralities along the magnetic field of the monopole due to the chiral separation effect. We find the stationary states of such a system, with vanishing total electric current and stationary axial current balanced by the chiral anomaly. In this solution, the monopole becomes "dressed" with an electric charge that is proportional to the averaged chiral density of the matter -- forming a chiral dyon. The interplay between the chiral effects on the one hand, and presence of magnetic field of the monopole on the other, may affect the evolution of the monopole density in the early Universe, contribute to the process of baryogenesis, and can also be instrumental for detection of relic monopoles using chiral materials.
