Jamming crossovers occur at zero temperature in assemblies of particles interacting via finite range repulsive potentials, when on increasing the density particles make contacts with those of subsequent coordination shells. Density anomalies, including an increased diffusivity upon isothermal compression and a negative thermal expansion coefficient, are the finite temperature signatures of the jamming crossovers. In this manuscript we show that the jamming crossovers are correlated to an increase of the non affine response of the system to density changes, and clarify that jammed systems evolve upon compression through subsequent Eshlby-like plastic instabilities.
