Abstract
Chiral plasma appears in several areas of physics, historically starting from primordial plasma in the early Universe, then in quark-gluon plasma produced in heavy-ion collisions, and, more recently, in Dirac and Weyl semimetals. A key feature of such media is the chiral anomaly, which leads to the non-conservation of the axial current and gives rise to anomaly-induced transport phenomena.
In this talk, I will explore the transport properties of chiral plasma in the presence of strong magnetic fields. Employing all-order gradient resummation, we derive constitutive relations for the vector and axial currents, parameterized by thirteen momentum- and magnetic-field-dependent transport coefficient functions. These functions are computed within a holographic model: U(1)V X U(1)A Maxwell-Chern-Simons theory in a Schwarzschild-Ads5 background in the probe limit.
As an application, I will revisit the phenomena of negative magnetoresistance and chiral magnetic waves beyond the naive hydrodynamic limit.
