noise in extremal dynamics
Rahul Chhimpa, Abha Singh, Avinash Chand Yadav
The Bak-Sneppen (BS) evolution model remains a well-studied example of self-organized criticality (SOC). We propose a simple variant of the BS model, where the global fitness fluct…

Continuous sample space reducing stochastic process
Rahul Chhimpa, Avinash Chand Yadav\
We propose a simple model for sample space reducing (SSR) stochastic process, where the dynamical variable denoting the size of the state space is continuous. In general, one can v…

Finite-time scaling for kinetic rough interfaces
Rahul Chhimpa, Avinash Chand Yadav
We consider discrete models of kinetic rough interfaces that exhibit space-time scale-invariance in height-height correlation. A generic scaling theory implies that the dynamical s…
