The Chiral Magnetic Effect (CME) is a phenomenon in which an electromagnetic current is generated along the direction of an external magnetic field in a quark-gluon plasma (QGP) due to the axial anomaly. This effect arises from the interplay between the topological charge of the QGP and the chirality of quarks. The CME is a result of the axial anomaly, which allows for the conversion of chirality into an electric current in the presence of a magnetic field. The magnitude of this current depends on the magnetic field strength, chirality, temperature, and baryon chemical potential. The CME is studied in the context of QCD, where the QGP is a phase of matter consisting of quarks and gluons. The axial anomaly plays a crucial role in the CME, as it allows for the generation of a current along the magnetic field. The CME is expected to be observed in heavy-ion collisions, where the QGP is produced. The effect is a direct experimental signature of the existence of topologically non-trivial gluon configurations and event-by-event P- and CP-violation. The CME can be understood through several approaches, including energy balance arguments, solving the Dirac equation, computing the thermodynamic potential, and using a derivative expansion of the effective action. These methods all lead to the conclusion that the current is proportional to the chiral chemical potential, which is related to the difference in the number of right- and left-handed fermions. The CME is also related to the behavior of the chiral charge density, which is conserved and depends on the magnetic field, temperature, and chemical potential. The current can be expressed in terms of the chiral charge density, and the dependence of the current on the chiral charge is analyzed in different limits, such as weak and strong magnetic fields. The results show that the Chiral Magnetic conductivity depends on temperature and chemical potential, and that the current decreases as these parameters increase. The CME is a key phenomenon in the study of QCD and provides insights into the behavior of the QGP in heavy-ion collisions. The CME is a manifestation of the axial anomaly and the interplay between chirality and magnetic fields in the QGP.The Chiral Magnetic Effect (CME) is a phenomenon in which an electromagnetic current is generated along the direction of an external magnetic field in a quark-gluon plasma (QGP) due to the axial anomaly.
