Retarded Correlators of Charge Transport in a Magnetic Field

Xuan Zhao, Qiuze Sun, Yi Wang +1

We study charge transport in a magnetized relativistic plasma using kinetic theory within the relaxation-time approximation. By exactly solving the linearized Boltzmann equation in…

Normal mode analysis within relativistic massive transport

Xin Lin, Qiu-Ze Sun, Xin-Hui Wu +1

In this paper, we address the normal mode analysis on the linearized Boltzmann equation for massive particles in the relaxation time approximation. One intriguing feature of massiv…

First-order spin magnetohydrodynamics

Zhe Fang, Koichi Hattori, Jin Hu

Based on recent papers, we discuss the formulation of the first-order relativistic spin magnetohydrodynamics (MHD) with the totally antisymmetric spin current and properties of the…

Anisotropic linear waves and breakdown of the momentum expansion in spin magnetohydrodynamics

Zhe Fang, Koichi Hattori, Jin Hu

We formulate spin magnetohydrodynamics (MHD) by including the magnetic-flux and total angular momentum conservation laws in the hydrodynamic framework. To specify the local angular…

Relaxation time approximation revisited and non-analytical structure in retarded correlators

Jin Hu

In this paper, we give a rigorous mathematical justification for the relaxation time approximation (RTA) model. We find that only the RTA with an energy-independent relaxation time…
