Improving the Density of Jammed Disordered Packings Using Ellipsoids
It is shown experimentally and with a new simulation algorithm that ellipsoids can randomly pack more densely and suggested that the higher density is directly related to the higher number of degrees of freedom per particle and thus the larger number of particle contacts required to mechanically stabilize the packing.
Jammed hard-particle packings: From Kepler to Bernal and beyond
This review describes the diversity of jammed configurations attainable by frictionless convex nonoverlapping (hard) particles in Euclidean spaces and for that purpose it stresses individual-packing
Supercooled liquids and the glass transition
Current theoretical knowledge of the manner in which intermolecular forces give rise to complex behaviour in supercooled liquids and glasses is discussed.
Geometric properties of random disk packings
Random packings ofN⩽2000 rigid disks in the plane, subject to periodic boundary conditions on a square primitive cell, have been generated by a concurrent construction which treats all disks on an
Axiomatic basis for spaces with noninteger dimension
Five structural axioms are proposed which generate a space SD with ’’dimension’’ D that is not restricted to the positive integers. Four of the axioms are topological; the fifth specifies an
Modeling heterogeneous materials via two-point correlation functions: basic principles.
This paper devise an efficient and isotropy-preserving construction algorithm, namely, the lattice-point algorithm to generate realizations of materials from their two-point correlation functions based on the Yeong-Torquato technique, and prove that S2(r) cannot completely specify a two-phase heterogeneous material alone.
Improved simulation of liquid water by molecular dynamics
Molecular dynamics calculations on a classical model for liquid water have been carried out at mass density 1 g/cm3 and at four temperatures. The effective pair potential employed is based on a
Molecular Dynamics Study of Liquid Water
A sample of water, consisting of 216 rigid molecules at mass density 1 gm/cm3, has been simulated by computer using the molecular dynamics technique. The system evolves in time by the laws of
Structure in aqueous solutions of nonpolar solutes from the standpoint of scaled-particle theory
Underlying assumptions have been examined in scaled-particle theory for the case of a rigid-sphere solute in liquid water. As a result, it has been possible to improve upon Pierotti's corresponding
