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…
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…
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…
