Title: Relativistic resistive magneto-hydrodynamics in high-energy heavy-ion collisions
Speaker: Prof. Chiho Nonaka (Hiroshima University )
Abstract: In high-energy heavy-ion collisions, the production of ultraintense electromagnetic fields by two colliding nuclei is one of the hottest topics. For the description of the time evolution of the ultraintense electromagnetic fields produced just after the collisions, the construction of the relativistic resistive magneto-hydrodynamics (RRMHD) Is indispensable.
Here, we construct a relativistic resistive magneto-hydrodynamic (RRMHD) numerical simulation code for high-energy heavy-ion collisions as a first designed code in the Milne coordinates. Also, we verify the semi-analytic solutions of the accelerating longitudinal expansion of relativistic resistive magneto-hydrodynamics in high-energy heavy-ion collisions in comparison with our numerical result. Next, we apply our RRMHD code to the analysis of the charge-dependent anisotropic flow in high-energy heavy-ion collisions. We conclude that the charge-dependent anisotropic flow is a good probe to extract the electrical conductivity of the QGP medium in high-energy heavy-ion experiments.
