AbstractWe perform a systematic numerical study of the effects of the particle-size ratio R >= 1 on the properties of jammed binary mixtures. We find that changing R does not qualitatively affect the critical scaling of the pressure and coordination number with the compression near the jamming transition, but the critical volume fraction at the jamming transition varies with R. Moreover, the static structure factor (density correlation) S(k) strongly depends on R and shows distinct long wave-length behaviors between large and small particles. Thus the previously reported behavior of S(k) similar to k in the long wavelength limit is only a special case in the R -> 1 limit, and cannot be simply generalized to jammed systems with R > 1.
