The role of asymmetric time delay and its structure in 1D swarmalators
Rommel Tchinda Djeudjo, Gourab Kumar Sar, Timoteo Carletti
Swarmalators are a class of coupled oscillators that simultaneously synchronize in both space and phase, providing a minimal model for systems ranging from biological microswimmers…
Interplay of sync and swarm: Theory and application of swarmalators
Gourab Kumar Sar, Kevin O'Keeffe, Joao U. F. Lizarraga +3
Swarmalators, entities that combine the properties of swarming particles with synchronized oscillations, represent a novel and growing area of research in the study of collective b…
A two-dimensional swarmalator model with higher-order interactions
Md Sayeed Anwar, Gourab Kumar Sar, Timoteo Carletti +1
We study a simple two-dimensional swarmalator model that incorporates higher-order phase interactions, uncovering a diverse range of collective states. The latter include spatially…
Dynamics of pulsating swarmalators on a ring
Samali Ghosh, Kevin O'Keeffe, Gourab Kumar Sar +1
We study a simple one-dimensional model of swarmalators, a generalization of phase oscillators that swarm around in space as well as synchronize internal oscillations in time. Prev…
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…
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…
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…
A solvable two-dimensional swarmalator model
Kevin O'Keeffe, Gourab Kumar Sar, Md Sayeed Anwar +3
Swarmalators are oscillators that swarm through space as they synchronize in time. Introduced a few years ago to model many systems which mix synchrony with self-assembly, they rem…
Directional synchrony among self-propelled particles under spatial influence
Suvam Pal, Gourab Kumar Sar, Dibakar Ghosh +1
Synchronization is one of the emerging collective phenomena in interacting particle systems. Its ubiquitous presence in nature, science, and technology has fascinated the scientifi…
Swarmalators on a ring with uncorrelated pinning
Gourab Kumar Sar, Kevin O'Keeffe, Dibakar Ghosh
We present a case study of swarmalators (mobile oscillators) which move on a 1D ring and are subject to pinning. Previous work considered the special case where the pinning in spac…
Flocking and swarming in a multi-agent dynamical system
Gourab Kumar Sar, Dibakar Ghosh
Over the past few decades, the research community has been interested in the study of multi-agent systems and their emerging collective dynamics. These systems are all around us in…
Anti-phase synchronization in a population of swarmalators
Samali Ghosh, Gourab Kumar Sar, Soumen Majhi +1
Swarmalators are oscillatory systems endowed with a spatial component, whose spatial and phase dynamics affect each other. Such systems can demonstrate fascinating collective dynam…
Collective dynamics of swarmalators with higher-order interactions
Md Sayeed Anwar, Gourab Kumar Sar, Matjaz Perc +1
Higher-order interactions shape collective dynamics, but how they affect transitions between different states in swarmalator systems is yet to be determined. To that effect, we her…
Solvable model of driven matter with pinning
Gourab Kumar Sar, Dibakar Ghosh, Kevin O'Keeffe
We present a simple model of driven matter in a 1D medium with pinning impurities, applicable to magnetic domains walls, confined colloids, and other systems. We find rich dynamics…
Pinning in a system of swarmalators
Gourab Kumar Sar, Dibakar Ghosh, Kevin O'Keeffe
We study a population of swarmalators (swarming/mobile oscillators) which run on a ring and are subject to random pinning. The pinning represents the tendency of particles to stick…
Resetting mediated navigation of active Brownian searcher in a homogeneous topography
Gourab Kumar Sar, Arnob Ray, Dibakar Ghosh +2
Designing navigation strategies for search time optimization remains of interest in various interdisciplinary branches in science. In here, we focus on microscopic self-propelled s…
Dynamics of swarmalators: A pedagogical review
Gourab Kumar Sar, Dibakar Ghosh
Swarmalators have emerged as a new paradigm for dynamical collective behavior of multi-agent systems due to the interplay of synchronization and swarming that they inherently incor…
Swarmalators under competitive time-varying phase interactions
Gourab K. Sar, Sayantan Nag Chowdhury, Matjaz Perc +1
Swarmalators are entities with the simultaneous presence of swarming and synchronization that reveal emergent collective behavior due to the fascinating bidirectional interplay bet…
