Scaling behavior in the number theoretic division model of self-organized criticality
Rahul Chhimpa, Avinash Chand Yadav
We revisit the number theoretic division model of self-organized criticality [Phys. Rev. Lett. 101, 158702 (2008)]. The model consists of a pool of ordered integers $\{2, 3,…

Fitness noise in the Bak-Sneppen evolution model in high dimensions
Rahul Chhimpa, Abha Singh, Avinash Chand Yadav
We study the Bak-Sneppen evolution model on a regular hypercubic lattice in high dimensions. Recent work [Phys. Rev. E 108, 044109 (2023)] has shown the emergence of the no…

noise in the Robin Hood model
Abha Singh, Rahul Chhimpa, Avinash Chand Yadav
We consider the Robin Hood dynamics, a one-dimensional extremal self-organized critical model that describes the evolution of low-temperature creep. One of the key quantities is th…
