Simple and efficient methods for local structural analysis in polydisperse hard disk systems Reviewed International journal
Daigo Mugita, Kazuyoshi Souno, Hiroaki Koyama, Taisei Nakamura, Masaharu Isobe
The Journal of Chemical Physics 160 ( 17 ) 174104 2024.05
Authorship：Last author Language：English Publishing type：Research paper (scientific journal) Publisher：AIP Publishing
In nonequilibrium statistical physics, quantifying the nearest (and higher-order) neighbors and free volumes of particles in many-body systems is crucial to elucidating the origin of macroscopic collective phenomena, such as glass/granular jamming transitions and various aspects of the behavior of active matter. However, conventional techniques (based on a fixed-distance cutoff or the Voronoi construction) have mainly been applied to equilibrated, homogeneous, and monodisperse particle systems. In this paper, we implement simple and efficient methods for local structure analysis in nonequilibrium, inhomogeneous, and polydisperse hard disk systems. We show how these novel methods can overcome the difficulties encountered by conventional techniques as well as demonstrate some applications.
