A fully relativistic lattice Boltzmann algorithm

Understand

Starting from the Maxwell-Juettner equilibrium distribution, we develop a relativistic lattice Boltzmann (LB) algorithm capable of handling ultrarelativistic systems with flat, but expanding, spacetimes.

• The algorithm is validated through simulations of quark-gluon plasma, yielding excellent agreement with hydrodynamic simulations.
• The present scheme opens the possibility of transferring the recognized computational advantages of lattice kinetic theory to the context of both weakly and ultra-relativistic systems.
