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…

High-order jamming crossovers and density anomalies.
It is demonstrated that particles interacting via core-softened potentials exhibit a series of successive density anomalies upon isothermal compression, leading to oscillations in the diffusivity and thermal expansion coefficient, with the latter reaching negative values, which correspond to zero-temperature high-order jamming crossovers.
The first jamming crossover: geometric and mechanical features.
It is shown that the first jamming crossover occurs at a well defined volume fraction, and that it induces a rearrangement of the force network causing a softening of the system.
Spatial Tessellations: Concepts and Applications of Voronoi Diagrams
This paper presents generalizations of the Voronoi Diagrams, a model of Spatial Interpolation, and some of the algorithms used in this study to derive these generalizations.
