Physics of strong electromagnetic fields in relativistic heavy-ion collisions

Koichi Hattori

I discuss several roles of the strong electromagnetic fields created by relativistic heavy-ion collisions. These phenomena call for theoretical and experimental developments to und…

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…

Preponderant Orbital Polarization in Relativistic Magnetovortical Matter

Kenji Fukushima, Koichi Hattori, Kazuya Mameda

We establish thermodynamic stability and gauge invariance in the magnetovortical matter of Dirac fermions under the coexistent rotation and strong magnetic field. The corresponding…

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…

Analytic solutions for the linearized first-order magnetohydrodynamics and implications for causality and stability

Zhe Fang, Koichi Hattori, Jin Hu

We address the linear-mode analysis performed near an equilibrium configuration in the fluid rest frame with a dynamical magnetic field perturbed on a constant configuration. We de…
