Title: Chiral Shock Waves
HEP Oct19 flyer
Abstract: We consider shock waves in relativistic chiral matter. We find that the conventional Rankine- Hugoinot relations have to be modified to take into account the physics of chiral transport phenomena. The entropy discontinuity in a weak shock wave is found to be linearly proportional to the pressure discontinuity when the effect of chiral transport becomes sufficiently large. We also show that rarefaction shock waves, which are absent in usual nonchiral fluids, can appear in chiral matter. These features are exemplified by shock propagation in dense neutrino matter in a vorticity in the hydrodynamic regime.
