Strongly Interacting Matter

The three dimensional plot of the phase diagram in (μq-T-E) space (μq is the quark chemical potential, T the temperature and E is the energy density of the system). Chiral symmetry in Quarkyonic matter is broken by the formation of the interweaving chiral spirals (ICS). The stair-like growth of the energy density along the μq axis expresses the discontinuous change in the shape of the Fermi sea.
