Chiral Shock Waves

Understand

We study the shock waves in relativistic chiral matter.

• We argue that the conventional Rankine-Hugoinot relations are modified due to the presence of chiral transport phenomena.
• We show that the entropy discontinuity in a weak shock wave is quadratic in the pressure discontinuity when the effect of chiral transport becomes sufficiently large.
• We also show that rarefaction shock waves, which do not exist in usual nonchiral fluids, can appear in chiral matter.
