Montenegro, D.
Causality of Polarizable Dissipative Fluids from Lagrangian Hydrodynamics / D.Montenegro, G.Torrieri. – Text : electronic // Physical Review D. – 2025. – Vol. 112, No. 3. – P. 034041. – URL: https://doi.org/10.1103/yjtd-qztf.
We perform a causality analysis on the dispersion relation of hydrodynamics with spin as well as shear and bulk viscosity, including the relaxation times for all these quantities. We find that the interplay of the three relaxational scales, for shear and bulk viscosity as well as polarization, leads to nontrivial effects on the dispersion relation. Unexpectedly, the presence of polarization leads to lower effective viscosity and a longer relaxation time, and the presence of viscosity leads to lower limits as well as upper ones on the group velocity and constraints relating polarization to viscosity relaxation times. We conclude with a qualitative discussion on how these results impact phenomenology, specifically the low effective viscosity in strongly interacting matter as well as shear-vorticity coupling.
