轴向异常、狄拉克海和手征磁效应

Axial anomaly, Dirac sea, and the chiral magnetic effect

Dmitri E. Kharzeev

摘要:

格里博夫认为轴向异常是真空中任意高动量带电费米子集体运动的表现。在存在外部磁场和手性不平衡的情况下,这种集体运动以电流的形式变得可以直接观察到-这就是手性磁效应(CME)。我给一个初步的介绍到CME的物理,并讨论一些最近的发展。

英文摘要:

Gribov viewed the axial anomaly as a manifestation of the collective motion of charged fermions with arbitrarily high momenta in the vacuum. In the presence of an external magnetic field and a chirality imbalance, this collective motion becomes directly observable in the form of the electric current - this is the chiral magnetic effect (CME). I give an elementary introduction into the physics of CME, and discuss some recent developments.
