Description
We develop a new form of the Wigner function for a relativistic gas of spin-1/2 particles in local equilibrium [1]. This new expression resolves the previously encountered issue with the normalization of the mean spin polarization and also leads to the generalized thermodynamic relations for perfect spin hydrodynamics, agreeing therefore with kinetic theory with classical spin treatment. Moreover, we demonstrate that perfect spin hydrodynamics based on the new equilibrium Wigner function is nonlinearly causal and stable [2]. These properties are crucial for constructing a physically meaningful and numerically consistent dynamical description of strongly interacting matter.
