Recent results on the jamming phase diagram

Systems of particles interacting via short-ranged repulsive forces are characterized by a jamming transition from a flowing to a disordered solid state, whose understanding is of great theoretical and practical relevance. The jamming phase diagram introduced by Liu and Nagel in 1998 provided a conceptual picture from which to investigate this transition, suggesting that the shear stress might play a role analogous to that of temperature in the jamming phenomenology. Here we highlight recent works which suggest qualitative changes in the shape of the diagram.
