Journal ArticleDOI
The role of heterogeneity on the spatiotemporal dynamics of host–parasite metapopulation ☆
TL;DR: Modelled a homogeneous metapopulation of the interacting host and parasite system, with closed boundary and dispersal limited to nearest neighbours, using the spatially explicit coupled map lattice approach, which shows spatiotemporally synchronous dynamics in the long-term.
Journal ArticleDOI
Phase-flip transition in coupled electrochemical cells
J. M. Cruz,J. Escalona,Punit Parmananda,Punit Parmananda,Rajat Karnatak,Awadhesh Prasad,Ramakrishna Ramaswamy,Ramakrishna Ramaswamy +7 more
TL;DR: When the time delay is varied a phase-flip transition is observed: the relative phase between the synchronized oscillations changes abruptly by pi, accompanied by an experimentally measurable discontinuous change in the frequency of the synchronous oscillators.
Journal ArticleDOI
Enhancing synchrony in chaotic oscillators by dynamic relaying.
Ranjib Banerjee,Dibakar Ghosh,E. Padmanaban,Ramakrishna Ramaswamy,L. M. Pecora,Syamal K. Dana +5 more
TL;DR: This work confirms the enhancing of critical coupling in the chaotic regimes of the Lorenz system, in the Rössler system in the absence of coupling delay, and in the Mackey-Glass system with delay coupling.
Journal ArticleDOI
Chimeras with multiple coherent regions
TL;DR: By modifying the details of the coupling, it is possible to obtain multiple chimeric states with a specified number of coherent regions and with specified phase relationships.
Journal ArticleDOI
Aperiodic nonchaotic attractors, strange and otherwise
TL;DR: New developments which include the creation of strange nonchaotic attractors in excitable systems, the elucidation of the mechanisms for the intermittent and fractalization routes to SNA as well as their potential applications are discussed.
