From Chiral Kinetic Theory To Relativistic Viscous Spin Hydrodynamics

Understand

In this work, we start with chiral kinetic theory and construct the spin hydrodynamic framework for a chiral spinor system.

• Using the 14-moment expansion formalism, we obtain the equations of motion of second-order dissipative relativistic fluid dynamics with non-trivial spin polarization density.
• In a chiral spinor system, the spin alignment effect could be treated in the same framework as the Chiral Vortical Effect (CVE).
• However, the quantum corrections due to fluid vorticity induce not only CVE terms in the vector/axial charge currents but also corrections to the stress tensor.
