Multi-cluster chimeras in phase oscillators with repulsive nonlocal coupling
Ayushi Saxena, Sangeeta Rani Ujjwal, Ram Ramaswamy
Local repulsive coupling tend to a desynchronize ensembles of globally coupled oscillators, but when the repulsive coupling is nonlocal, multi-cluster chimeras can result. In this…

Slow driving induced multistability and remote synchronization in chaotic Chua's circuit
Tuhin Mahanty, Ayushi Saxena, Sangeeta Rani Ujjwal
We study the response of Chua's circuit driven by a chaotic signal of variable time-scale. We observe that when the frequency of the drive is significantly lower than that of the r…

Diversity mitigates polarization and consensus in opinion dynamics
Sidharth Pradhan, Sangeeta Rani Ujjwal
We study the opinion dynamics in a population by considering a variant of Kuramoto model where the phase of an oscillator represents the opinion of an individual on a single topic.…
