Description

In this talk, we shall discuss the finite temperature physics of a magnetohydrodynamic chiral plasma. This can be understood as a system with an axial $U(1)_A$ current that is afflicted by an Adler-Bell-Jackiw (ABJ) anomaly, where the corresponding vector $U(1)_V$ current has been coupled to dynamical electromagnetism. In modern language, the system has a 1-form global symmetry associated with the conservation of magnetic flux and the global axial 0-form symmetry is broken by the ABJ anomaly. We will study this problem by analyzing a holographic model with the above symmetry structure.
