Divergence and resummation of the moment expansion for an ultrarelativistic gas in Bjorken flow
Caio V. P. de Brito, David Wagner, Gabriel S. Denicol +1
In this letter, we demonstrate for the first time that the moment expansion for an ultrarelativistic gas undergoing Bjorken flow diverges. We then show how this series can be resum…

Damping of spin waves
David Wagner, Masoud Shokri, Dirk H. Rischke
We show that, in ideal-spin hydrodynamics, the components of the spin tensor follow damped wave equations. The damping rate is related to nonlocal collisions of the particles in th…
