Relativistic dissipative magnetohydrodynamics

I will be presenting my research on the subject of Relativistic Magnetohydrodynamics (RMHD). The focus of the discussion will be on the dynamic interactions of relativistic fluids in the presence of strong magnetic fields, particularly in the context of heavy-ion collisions. In this presentation, I will discuss the derivation of RMHD equations from the Boltzmann equation using the method of moments. Emphasis will be placed on the unique characteristics of these equations compared to traditional hydrodynamics, with a specific focus on the evolution of the shear stress tensor.

The talk will delve into the significant impact of intense magnetic fields generated during early heavy-ion collisions, reaching peaks of $10^{19}$ gauss (RHIC) and $10^{20}$ gauss (LHC). These magnetic fields play a crucial role in influencing the dynamics of the Quark-Gluon Plasma formed during the initial stages of these collisions. Additionally, I will touch upon the application of RMHD in the context of Bjorken flow, providing insights into its broader relevance.
