Description

Taking into account the recent measurements of the spin-polarization of particles produced at RHIC and LHC, the self-consistent formulation of relativistic fluid mechanics for spin-polarized media subjected to a large magnetic field is of great interest to the relativistic heavy-ion collisions community [1]. To meet this need, we formulate a relativistic kinetic theory for spin-polarized particles under the influence of a magnetic field and derive equations of motion for relativistic dissipative non-resistive magnetohydrodynamics [2]. In the kinetic equation, we utilize a relaxation-time approximation for the collisional kernel and compute respective nonequilibrium corrections to the phase-space distribution function. We show how our framework naturally leads to the relativistic analogs of Einstein-de Haas and Barnett's effects. Moreover, we find respective transport coefficients and demonstrate the emergence of the link between spin and magnetic field at gradient order.
