Chiral anomalous effects in relativistic plasmas are reviewed. The essence of chiral separation and chiral magnetic effects is explained in simple terms. Qualitative differences between the two phenomena, both of which are triggered by background electromagnetic fields, are highlighted. It is shown how an interplay of the chiral separation and chiral magnetic effects could lead to a new collective plasma mode, called the chiral magnetic wave. It is argued that the chiral magnetic wave is overdamped in weakly interacting plasmas. Its fate in a strongly interacting quark-gluon plasma is less clear, especially in the presence of a superstrong magnetic field. The observational signatures of the chiral anomalous effects are discussed briefly.

  1. Photon emission from weakly magnetized neutral pions

    hep-ph 2025-12 conditional novelty 6.0 of 10

    In a proton-loop hadronic model, a weak magnetic field suppresses π0→γγ at O(|eB|²/m_P⁴), with a small anisotropy strongest for pion momenta perpendicular to the field.

  2. Effect of chiral imbalance on the electrical conductivity of hot and dense quark matter using Green-Kubo Method within the 2-flavour gauged NJL model

    hep-ph 2024-11 conditional novelty 5.0 of 10

    Electrical conductivity to temperature ratio in quark matter decreases with increasing chiral chemical potential in the NJL model, most strongly at low temperature.
