Topological generalization of the rigid-nonrigid transition in soft-sphere and hard-sphere fluids
Tae Jun Yoon, Emanuel A. Lazar, Min Young Ha +2
A fluid particle changes its dynamics from diffusive to oscillatory as the system density increases up to the melting density. Hence, the notion of the Frenkel line was introduced…

Topological Characterization of Rigid-Nonrigid Transition across the Frenkel Line
Tae Jun Yoon, Min Young Ha, Emanuel A. Lazar +2
The dynamics of supercritical fluids, a state of matter beyond the gas-liquid critical point, changes from diffusive to oscillatory motions at high pressure. This transition is bel…

VoroTop: Voronoi Cell Topology Visualization and Analysis Toolkit
Emanuel A. Lazar
This paper introduces a new open-source software program called VoroTop, which uses Voronoi topology to analyze local structure in atomic systems. Strengths of this approach includ…
