Effect of reactive targets on diffusive transport with intermittent restarts
Samali Ghosh, Suvam Pal, Dibakar Ghosh +1
We study search processes in a complex environment using the strategy of stochastic resetting. A common occurrence in these environments is targets with finite reactivity. Stochast…
Dispersal-induced survival of predators in metacommunities due to transient chaos
Samali Ghosh, Arnob Ray, Everton S. Medeiros +5
Dispersal networks critically shape the fate of ecological communities, yet the mechanisms linking connectivity and persistence remain poorly understood. We show that an interplay…
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…
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…
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…
