An Introduction to S(5,8,24)
… codes, finite simple groups, and sphere packings in a truly remarkable way. This thesis discusses the underlying structure of S(5,8,24), its construction via the (24,12) Golay code, as well its automorphism group, which is the Mathieu group M24, a member of the sporadic simple …

On the complexity of energy landscapes: algorithms and a direct test of the Edwards conjecture
… entropy of two and three-dimensional jammed packings. By means of numerical simulation we show the extensivity of the granular entropy as proposed by S.F. Edwards for three-dimensional jammed soft-sphere packings and produce a direct test of the Edwards conjecture for the equivalent two …

Random close packing (RCP) of equal spheres: structure and implications for use as a model porous medium
… the Finney Random Close Packing (RCP) of equal spheres has been analysed, together with the influence which such structure exerts over the capillary pressure characteristics of geometrically similar sphere packings. The analysis is centred on the simplicial, or Delaunay cell, which is an …

Unearthing the Anticrystal: Criticality in the Linear Response of Disordered Solids
… idealized system composed of frictionless soft spheres at zero temperature that, when compressed, undergos a jamming phase transition with diverging length scales and clean power-law signatures. This critical point is the cornerstone of a much larger ``jamming scenario" that has the potential to …

Transition between Flow Regimes in Porous Media Using Magnetic Resonance Velocimetry: From Laminar to Turbulent
… and turbulent flow regimes, was examined in sphere packings. Further understanding of the fundamental fluid dynamics was derived based on the pore-scale flow visualisation using magnetic resonance velocimetry (MRV). Spiral imaging was selected as the ultrafast imaging protocol to probe the …

Thermodynamics of Micellar Lyotropic Liquid Crystals
… micelles packed on a lattice. Typically, LLC sphere packings include high-symmetry body-centered cubic (BCC), face-centered cubic (FCC), and hexagonally closest-packed (HCP) structures. Recently, a giant tetragonal σ phase containing 30 micelles of five different sizes was discovered in the …

Rigidity and Fluidity in Living and Nonliving Matter
… as applied to frictionless, repulsive soft sphere packings in two dimensions with the</p> <p>introduction of the jamming graph. Minimal rigidity is a purely combinatorial property encoded via Laman's theorem in two dimensions. It constrains the global, average coordination number of the …
