On Mixed Sphere Packings
نویسنده
چکیده
Balls of two diierent radii r 1 < r 2 can trivially be packed in E 3 with density better than the classical packing density 3 L = 0:74048. .. , if r 1 =r 2 0:41::. We show that this even holds for r 1 =r 2 = 0:623. .. Further we show, under strong restrictions, that r 1 =r 2 close to 1 does not yield a density > 3 L. These results correspond to similar results on circle packings in the plane

Density Doubling, Double-circulants, and New Sphere Packings
New nonlattice sphere packings in dimensions 20, 22, and 44–47 that are denser than the best previously known sphere packings were recently discovered. We extend these results, showing that the density of many sphere packings in dimensions just below a power of 2 can be doubled using orthogonal binary codes. This produces new dense sphere packings in Rn for n = 25, 26, . . . , 31 and 55, 56, . ...
متن کاملCharacterization of maximally random jammed sphere packings. II. Correlation functions and density fluctuations.
In the first paper of this series, we introduced Voronoi correlation functions to characterize the structure of maximally random jammed (MRJ) sphere packings across length scales. In the present paper, we determine a variety of different correlation functions that arise in rigorous expressions for the effective physical properties of MRJ sphere packings and compare them to the corresponding sta...
متن کاملPhase diagram and structural diversity of the densest binary sphere packings.
The densest binary sphere packings have historically been very difficult to determine. The only rigorously known packings in the α-x plane of sphere radius ratio α and relative concentration x are at the Kepler limit α=1, where packings are monodisperse. Utilizing an implementation of the Torquato-Jiao sphere-packing algorithm [S. Torquato and Y. Jiao, Phys. Rev. E 82, 061302 (2010)], we presen...
متن کاملSphere Packings and Error-correcting Codes
Error-correcting codes are used in several constructions for packings of equal spheres in ^-dimensional Euclidean spaces E. These include a systematic derivation of many of the best sphere packings known, and construction of new packings in dimensions 9-15, 36, 40, 48, 60, and 2 for m g 6. Most of the new packings are nonlattice packings. These new packings increase the previously greatest know...
متن کاملConfined disordered strictly jammed binary sphere packings.
Disordered jammed packings under confinement have received considerably less attention than their bulk counterparts and yet arise in a variety of practical situations. In this work, we study binary sphere packings that are confined between two parallel hard planes and generalize the Torquato-Jiao (TJ) sequential linear programming algorithm [Phys. Rev. E 82, 061302 (2010)] to obtain putative ma...
