Holographic Anomalous Conductivities and the Chiral Magnetic Effect

Understand

We calculate anomaly induced conductivities from a holographic gauge theory model using Kubo formulas, making a clear conceptual distinction between thermodynamic state variables such as chemical potentials and external background fields.

• This allows us to pinpoint ambiguities in previous holographic calculations of the chiral magnetic conductivity.
• We also calculate the corresponding anomalous current three-point functions in special kinematic regimes.
• We compare the holographic results to weak coupling calculations using both dimensional regularization and cutoff regularization.
