Electromagnetic fields with electric and chiral magnetic conductivities in heavy ion collisions

Understand

We derive analytic formula for electric and magnetic fields produced by a moving charged particle in a conducting medium with the electric conductivity $\sigma$ and the chiral magnetic conductivity $\sigma_{\chi}$.

• We use the Green function method and assume that $\sigma_{\chi}$ is much smaller than $\sigma$.
• The compact algebraic expressions for electric and magnetic fields without any integrals are obtained.
• They recover the Lienard-Wiechert formula at vanishing conductivities.
