Description
In this talk, we present a kinetic-theory investigation of charge transport properties of a magnetized relativistic plasma within kinetic theory, solving the linearized relativistic Boltzmann equation with a constant magnetic field in the relaxation-time approximation. Exploiting cylindrical symmetry, we derive an analytic solution for the perturbed distribution function in terms of Bessel-series expansion, and compute the full retarded current-current correlators satisfying Ward identities. In the hydrodynamic limit, we extract the anisotropic diffusive modes: the longitudinal diffusion coefficient remains unaffected by the magnetic field, while the transverse coefficient is significantly suppressed, scaling as $1/B_0^2$ in the strong-field limit. Beyond hydrodynamics, we identify branch cuts in the frequency plane associated with non-hydrodynamic modes, with $l=0$ harmonic corresponding to Landau damping and $l \neq 0$ channels to cyclotron damping via relativistic Doppler effects.
