Formulating two-fluid dissipative magnetohydrodynamics for general-relativistic plasmas

Relativistic plasmas are central to the study of black hole accretion, jet physics, neutron star mergers, and compact object magnetospheres. I will describe a fully relativistic covariant 14-moment based two-fluid system appropriate for the study of electron-ion or electron-positron plasmas, which is obtained from the relativistic Boltzmann-Vlasov equation. Crucially, this new formulation can account for non-ideal effects, such as anisotropic pressures and heat fluxes. Finally, I will show how relativistic two-fluid plasmas can be recast into a dissipative single fluid formulation with dissipative corrections, while still maintaining self-consistent evolution equations for electron temperature and momentum.
