Query: Absorbing-state transitions in granular materials close to jamming   We consider a model for driven particulate matter in which absorbing states
can be reached both by particle isolation and by particle caging. The model
predicts a non-equilibrium phase diagram in which analogues of hydrodynamic and
elastic reversibility emerge at low and high volume fractions respectively,
partially separated by a diffusive, non-absorbing region. We thus find a single
phase boundary that spans the onset of chaos in sheared suspensions to the
onset of yielding in jammed packings. This boundary has the properties of a
non-equilibrium second order phase transition, leading us to write a Manna-like
mean-field description that captures the model predictions. Dependent on
contact details, jamming marks either a direct transition between the two
absorbing states, or occurs within the diffusive region.
