Ripples in the bottom of the potential energy landscape of metallic glass
In the absence of periodicity, the structure of glass is ill-defined, and a large number of
structural states are found at similar energy levels. However, little is known about how these …

Interplay between an absorbing phase transition and synchronization in a driven granular system
Absorbing phase transitions (APTs) are widespread in nonequilibrium systems, spanning
condensed matter, epidemics, earthquakes, ecology, and chemical reactions. APTs feature …

Absorbing phase transitions and dynamic freezing in running active matter systems
C Reichhardt, CJO Reichhardt - Soft Matter, 2014 - pubs.rsc.org
We examine a two-dimensional system of sterically repulsive interacting disks where each
particle runs in a random direction. This system is equivalent to a run-and-tumble dynamics …
