Finite-volume scheme for first-order viscoresistive relativistic magnetohydrodynamics
Ruben Lier, Jay Armas, Oliver Porth
We present a numerical implementation of dissipative relativistic magnetohydrodynamics based on Bemfica-Disconzi-Noronha-Kovtun (BDNK) theory, in which first-order corrections rend…

Chapman-Enskog expansion for chirally colliding disks
Ruben Lier, Paweł Matus
We study a two-dimensional gas of hard disks undergoing chiral, energy- and momentum-conserving collisions. We propose a simple chiral collision rule and show that it can effective…
