arXiv preprint arXiv:2310.07481, 2023•arxiv.orgUnder relaxation time approximation, we obtain an iterative solution to the relativistic
Boltzmann equation in generic stationary spacetime. This solution provides a scheme to
study non-equilibrium system order by order. As a specific example, we analytically
calculated the covariant expressions of the particle flow and the energy momentum tensor
up to the first order in relaxation time. Finally and most importantly, we present all 14 kinetic
coefficients for a neutral system, which are verified to satisfy the Onsager reciprocal relation …

As a specific example, we analytically calculated the covariant expressions of the particle flow and the energy momentum tensor up to the first order in relaxation time. Finally and most importantly, we present all 14 kinetic coefficients for a neutral system, which are verified to satisfy the Onsager reciprocal relation and guarantee a non-negative entropy production.
