量子测量与手征磁效应

Quantum measurements and chiral magnetic effect

V. Shevchenko

摘要:

在量子测量理论的框架内讨论了各向异性对磁场中电流涨落的影响。结果表明,对于均匀磁场中的自由费米子,其各向异性与手征磁效应的符号相同,并与三角形反常有关。相应的退相干泛函包含异常的非对角项,导致相反的P-宇称观测值之间的波动相关。

英文摘要:

The effect of anisotropy for fluctuations of electric currents in magnetic field is addressed within framework of quantum measurements theory. It is shown that for free fermions in uniform magnetic field the anisotropy is of the same sign as one expects for chiral magnetic effect and is related to triangle anomaly. The corresponding decoherence functional contains anomalous off-diagonal terms leading to correlation of fluctuations between observables of opposite P-parity.
