Description

In my talk, I will give a comprehensive overview of our group's recent results in spin hydrodynamics, including:
- generalized thermodynamic relations [1],
- the twofold expansion, in spin polarization and in gradients [2],
- stability and causality [3, 4],
- boost-invariant solutions [5, 6, 7],
- the new local equilibrium Wigner function for spin-1/2 particles [8, 9],
- discussion of Fermi-Dirac [10, 11] and Bose-Einstein statistics,
- extension of the spin hydrodynamics framework to spin-1 particles [12],
- preliminary numerical solutions of dissipative spin hydrodynamics, with transfer between the orbital and the spin part of the total angular momentum.
