Quantification of order in the Lennard-Jones system

The structural order found in equilibrium and nonequilibrium states of the shifted-force Lennard-Jones system was investigated. As such, a number of accurate methods were used to determine the underlying phase behavior. Two forms of order, bond-orientational and translational, were then examined using simple metrics introduced recently. The results lead to a number of new insights intot he structure of simple systems interacting via spherically symmetric forces, such as colloidal particles and rare gases.
