Public Release: 1-Feb-2017 The shape of melting in two dimensions
As part of her team's research into matter's tendency to self-organize, Sharon Glotzer of the University of Michigan ran a series of hard particle simulations to study melting in two-dimensional (2-D) systems. Specifically, the team explored how particle shape affects the physics of a 2-D solid-to-fluid melting transition.
