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…
Explosive synchronization in coupled stars
Ruby Varshney, Kaustubh Manchanda, Haider Hasan Jafri
We study the effect of network topology on the collective dynamics of an oscillator ensemble. Specifically, we explore explosive synchronization in a system of interacting star net…
Effect of noise on explosive synchronization
Ruby Varshney, Haider Hasan Jafri
In this paper we explore the emergence of explosive synchronization (ES) in a star network by considering the dynamics of coupled phase oscillators in the presence of noise. While…
Explosive transitions in interacting star networks
Anjuman Ara Khatun, Ruby Varshney and, Haider Hasan Jafri
We study transition to phase synchronization in an ensemble of Stuart-Landau oscillators interacting on a star network. We observe that by introducing frequency weighted coupling a…
Critical neuronal avalanches in levels model under noisy drive
Abdul Quadir, Haider Hasan Jafri, Avinash Chand Yadav
We consider a neuronal levels model that exhibits critical avalanches satisfying power-law distribution. The model has recently explained a change in the scaling exponent from 3/2…
Collective Dynamics of coupled Lorenz oscillators near the Hopf Boundary: Intermittency and Chimera states
Anjuman Ara Khatun, Yusra Ahmed Saeed, Nirmal Punetha +1
We study collective dynamics of networks of mutually coupled identical Lorenz oscillators near subcritical Hopf bifurcation. This system shows induced multistable behavior with int…
Finite-size scaling of critical avalanches
Avinash Chand Yadav, Abdul Quadir, Haider Hasan Jafri
We examine probability distribution for avalanche sizes observed in self-organized critical systems. While a power-law distribution with a cutoff because of finite system size is t…
Controlling chimera states in multilayer network through linear augmentation
Anjuman Ara Khatun, Haider Hasan Jafri
In this work we present a method to control chimera states through linear augmentation. Using an ensemble of globally coupled oscillators, we demonstrate that control over the spat…
Occurrence and stability of chimera states in multivariable coupled flows
Anjuman Ara Khatun, Haider Hasan Jafri
Study of collective phenomenon in populations of coupled oscillators are a subject of intense exploration in physical, biological, neuronal and social systems. Here we propose a sc…
