Fitness Fluctuations and Correlation Time Scaling in the Barycentric Bak-Sneppen Model
Abdul Quadir, Haider Hasan Jafri
We consider the barycentric version of the Bak-Sneppen model, a one-dimensional self-organized critical model that describes generalized Keynesian beauty contests with a local inte…

Extreme events scaling in self-organized critical models
Abdul Quadir, Haider Hasan Jafri
We study extreme events of avalanche activities in finite-size two-dimensional self-organized critical (SOC) models, specifically the stochastic Manna model (SMM) and the Bak-Tang-…

Scaling of Extreme Events in 2d BTW Sandpile
Abdul Quadir, Haider Hasan Jafri
We study extreme events in a finite-size 2D Abelian sandpile model, specifically focusing on avalanche area and size. Employing the approach of Block Maxima, the study numerically…
