Rigidity percolation by next-nearest-neighbor bonds on generic and regular isostatic lattices
We study rigidity percolation transitions in two-dimensional central-force isostatic lattices,
including the square and the kagome lattices, as next-nearest-neighbor bonds (“braces”) are …

Jamming percolation in three dimensions
We introduce a three-dimensional model for jamming and glasses, and prove that the
fraction of frozen particles is discontinuous at the directed-percolation critical density. In …

Hydrodynamics in kinetically constrained lattice-gas models
Kinetically constrained models are lattice-gas models that are used for describing glassy
systems. By construction, their equilibrium state is trivial and there are no equal-time …

Relation between structure of blocked clusters and relaxation dynamics in kinetically constrained models
We investigate the relation between the cooperative length and relaxation time, represented,
respectively, by the culling time and the persistence time, in the Fredrickson-Andersen, Kob …

Finite-density effects in the Fredrickson-Andersen and Kob-Andersen kinetically-constrained models
We calculate the corrections to the thermodynamic limit of the critical density for jamming in
the Kob-Andersen and Fredrickson-Andersen kinetically-constrained models, and find them …

Kinetically constrained model for gravity-driven granular flow and clogging
We add extreme driving to the Kob-Andersen kinetically constrained lattice-gas model in
order to mimic the effect of gravity on dense granular systems. For low particle densities, the …

Constraint relaxation leads to jamming
Adding transitions to an equilibrium system increases the activity. Naively, one would expect
this to hold also in out-of-equilibrium systems. We demonstrate, using relatively simple …

Rigidity in Isostatic Networks: Disorder, Criticality, and Topological States
L Zhang - 2019 - deepblue.lib.umich.edu
Rigidity is one of the central themes in soft condensed matter physics. There has been
enduring research interest in understanding rigidity and softness of materials. The purpose …
