Dynamics of swarmalators in the presence of a contrarian
Gourab Kumar Sar, Sheida Ansarinasab, Fahimeh Nazarimehr +3
Swarmalators are entities that combine the swarming behavior of particles with the oscillatory dynamics of coupled phase oscillators and represent a novel and rich area of study wi…
A strategy to control synchronized dynamics in swarmalator systems
Gourab Kumar Sar, Md Sayeed Anwar, Martin Moriamé +2
Synchronization forms the basis of many coordination phenomena in natural systems, enabling them to function cohesively and support their fundamental operations. However, there are…
On forced swarmalators that move in higher-dimensional spaces
Md Sayeed Anwar, Dibakar Ghosh, Kevin O'Keeffe
We study the collective dynamics of swarmalators subjected to periodic (sinusoidal) forcing. Although previous research focused on the simplified case of motion in a one-dimensiona…
Effects of coupling range on the dynamics of swarmalators
Gourab Kumar Sar, Kevin O'Keeffe, Dibakar Ghosh
We study a variant of the one-dimensional swarmalator model where the units' interactions have a controllable length scale or range. We tune the model from the long-range regime, w…
Complexity measure of extreme events
Dhiman Das, Arnob Ray, Chittaranjan Hens +5
Complexity is an important metric for appropriate characterization of different classes of irregular signals, observed in the laboratory or in nature. The literature is already ric…
The forced one-dimensional swarmalator model
Md Sayeed Anwar, Dibakar Ghosh, Kevin O'Keeffe
We study a simple model of swarmalators subject to periodic forcing and confined to move around a one-dimensional ring. This is a toy model for physical systems with a mix of sync,…
Synchronization in adaptive higher-order networks
Md Sayeed Anwar, S. Nirmala Jenifer, Paulsamy Muruganandam +2
Many natural and human-made complex systems feature group interactions that adapt over time in response to their dynamic states. However, most of the existing adaptive network mode…
Coprime networks of the composite numbers: pseudo-randomness and synchronizability
Md Rahil Miraj, Dibakar Ghosh, Chittaranjan Hens
In this paper, we propose a network whose nodes are labeled by the composite numbers and two nodes are connected by an undirected link if they are relatively prime to each other. A…
Dynamical robustness of network of oscillators
Soumen Majhi, Biswambhar Rakshit, Amit Sharma +2
Most complex systems are nonlinear, relying on emergent behavior from interacting subsystems, often characterized by oscillatory dynamics. Collective oscillatory behavior is essent…
Global synchronization in generalized multilayer higher-order networks
Palash Kumar Pal, Md Sayeed Anwar, Matjaz Perc +1
Networks incorporating higher-order interactions are increasingly recognized for their ability to introduce novel dynamics into various processes, including synchronization. Previo…
Amplitude responses of swarmalators
Samali Ghosh, Suvam Pal, Gourab Kumar Sar +1
Swarmalators are entities that swarm through space and sync in time and are potentially considered to replicate the complex dynamics of many real-world systems. So far, the interna…
Cluster formation due to repulsive spanning trees in attractively coupled networks
Sayantan Nag Chowdhury, Md Sayeed Anwar, Dibakar Ghosh
Ensembles of coupled nonlinear oscillators are a popular paradigm and an ideal benchmark for analyzing complex collective behaviors. The onset of cluster synchronization is found t…
Self-organized bistability on globally coupled higher-order networks
Md Sayeed Anwar, Nikita Frolov, Alexander E. Hramov +1
Self-organized bistability (SOB) stands as a critical behavior for the systems delicately adjusting themselves to the brink of bistability, characterized by a first-order transitio…
