Causality and Stability of First-Order Relativistic Spin Hydrodynamics with Conserved Charges
Wei Lu, Yang Zhong, Sheng-Qin Feng
We study the causality and stability of first-order relativistic spin hydrodynamics with particle-number conservation. By deriving the complete dispersion relations of linear pertu…

Causality and stability analysis of relativistic spin hydrodynamics: Insights from a nonvanishing spin density background
Wei Lu, Yang Zhong, Sheng-Qin Feng
We investigate the stability and causality of relativistic spin hydrodynamics in the presence of a nonvanishing spin density background, assuming that the spin chemical potential $…
