Fermi-liquid view of viscosity in cold and dense nucleon matter
Jianing Li, Weiyao Ke, Jin Hu
We develop a framework to calculate transport properties in cold, dense relativistic quasiparticle system within the Fermi-liquid theory at the mean-field level. Building on our pr…
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…
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…
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…
Analytical Solution of the Nonlinear Relativistic Boltzmann Equation
Jin Hu
We provide an exact analytical solution to the nonlinear relativistic Boltzmann equation for a homogeneous, anisotropically scattering massless gas. Utilizing a BKW-like trial solu…
