Topology Controlled Potts Coarsening
J. Denholm, S. Redner
We uncover unusual topological features in the long-time relaxation of the -state kinetic Potts ferromagnet on the triangular lattice that is instantaneously quenched to zero te…
Reality Inspired Voter Models: A Mini-Review
S. Redner
This mini-review presents extensions of the voter model that incorporate various plausible features of real decision-making processes by individuals. Although these generalizations…
Residence Time Near an Absorbing Set
J. Randon-Furling, S. Redner
We determine how long a diffusing particle spends in a given spatial range before it dies at an absorbing boundary. In one dimension, for a particle that starts at and is abs…
The Advantage of Foraging Myopically
C. L. Rager, U. Bhat, O. Bénichou +1
We study the dynamics of a \emph{myopic} forager that randomly wanders on a lattice in which each site contains one unit of food. Upon encountering a food-containing site, the fora…
Edge fires drive the shape and stability of tropical forests
Laurent Hébert-Dufresne, Adam F. A. Pellegrini, Uttam Bhat +3
In tropical regions, fires propagate readily in grasslands but typically consume only edges of forest patches. Thus forest patches grow due to tree propagation and shrink by fires…
