Novel formulation of relativistic magnetohydrodynamics and phases of collective excitations with a chirality imbalance

I will discuss a novel formulation of relativistic magnetohydrodynamics that describes the low-energy behaviors of a fluid in a dynamical magnetic field. This is done in a way faithful to the symmetries of the system, i.e., conservations of the energy-momentum and of the magnetic flux from the magnetic one-form symmetry. I will also discuss an extension to the systems with chirality imbalances and a new helical instability emerging there as a solution of the chiral magneto hydrodynamics.
