[Journal Club] Dissipative Spin Dynamics in Relativistic Matter

Avdhesh Kumar

Using the classical description of spin degrees of freedom, we extend recent formulation of the perfect-fluid hydrodynamics for spin-polarized fluids to the case including dissipation. Our work is based on the analysis of classical kinetic equations for massive particles with spin 1/2, with the collision terms treated in the relaxation time approximation. The kinetic theory framework determines the structure of viscous and diffusive terms and allows to explicitly calculate a complete set of new kinetic coefficients that characterize dissipative spin dynamics.
