Explosive synchronization in coupled nonlinear oscillators on multiplex network
Umesh Kumar Verma, G. Ambika
We report the emergence of explosive synchronization in a multiplex network where oscillators on the first layer are coupled with attractive coupling and those on the second layer,…
Emergent Dynamics and Spatio Temporal Patterns on Multiplex Neuronal Networks
Umesh Kumar Verma, G. Ambika
We present a study on the emergence of a variety of spatio temporal patterns among neurons that are connected in a multiplex framework, with neurons on two layers with different fu…
Frequency chimera state induced by differing dynamical timescales
Sneha Kachhara, G. Ambika
We report the occurrence of a self-emerging frequency chimera state in spatially extended systems of coupled oscillators, where the coherence and incoherence are defined with respe…
Tipping induced by multiplexing on two layer networks
Umesh Kumar Verma, G. Ambika
We report the study of sudden transitions or tipping in a collection of systems induced due to multiplexing with another network of systems. The emergent dynamics of oscillators on…
Amplitude chimera and chimera death induced by external dynamical agents
Umesh Kumar Verma, G. Ambika
We report the emergence of stable amplitude chimeras and chimera death in a two-layer network where one layer has an ensemble of identical nonlinear oscillators interacting directl…
Role of time scales and topology on the dynamics of complex networks
Kajari Gupta, G. Ambika
The interplay between time scales and structural properties of complex networks of nonlinear oscillators can generate many interesting phenomena, like amplitude death, cluster sync…
