Phases of granular segregation in a binary mixture [link]Paper  doi  abstract   bibtex   
We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with the surface of a vibrating horizontal tray. Three distinct phases of the mixture are established viz; binary gas (unsegregated), segregation liquid and segregation crystal. Their ranges of existence are mapped out as a function of the system's primary control parameters using a number of measures based on Voronoi tessellation. We study the associated transitions and show that segregation can be suppressed is the total filling fraction of the granular layer, \$C\$, is decreased below a critical value, \$C_\{c\}\$, or if the dimensionless acceleration of the driving, \${\textbackslash}gamma\$, is increased above a value \${\textbackslash}gamma_\{c\}\$.
