Exact results on the hydrodynamics of certain kinetically-constrained hopping processes
Adam J. McRoberts, Vadim Oganesyan, Antonello Scardicchio
We consider a model of interacting random walkers on a triangular chain and triangular lattice, where a particle can move only if the other two sites of the triangle are unoccupied…

A kinetically constrained model exhibiting non-linear diffusion and jamming
Abhishek Raj, Vadim Oganesyan, Antonello Scardicchio
We present a classical kinetically constrained model of interacting particles on a triangular ladder, which displays diffusion and jamming and can be treated by means of a classica…

Diffusion cascade in a model of interacting random walkers
Abhishek Raj, Paolo Glorioso, Sarang Gopalakrishnan +1
We consider the relaxation of finite-wavevector density waves in a facilitated classical lattice gas. Linear hydrodynamics predicts that such perturbations should relax exponential…
