Adaptive control in dynamical systems using reservoir computing
Swarnendu Mandal, Swati Chauhan, Umesh Kumar Verma +2
We demonstrate a data-driven technique for adaptive control in dynamical systems that exploits the reservoir computing method. We show that a reservoir computer can be trained to p…
Recovery of synchronized oscillations on multiplex networks by tuning dynamical time scales
Aiwin T Vadakkan, Umesh Kumar Verma, G. Ambika
The heterogeneity among interacting dynamical systems or variations in the pattern of their interactions occur naturally in many real complex systems. Often they lead to partially…
Solitary death in coupled limit-cycle oscillators with higher-order interactions
Subhasanket Dutta, Umesh Kumar Verma, Sarika Jalan
Coupled limit cycle oscillators with pairwise interactions depict phase transitions to amplitude or oscillation death. This Letter introduces a scheme for higher-order interactions…
Explosive death in coupled oscillators with higher-order interactions
Richita Ghosh, Umesh Kumar Verma, Sarika Jalan +1
We investigate the dynamical evolution of globally connected Stuart-Landau oscillators coupled through conjugate or dis-similar variables on simplicial complexes. We report a first…
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…
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…
Advent of Extreme Events in Predator Populations
Sudhanshu Shekhar Chaurasia, Umesh Kumar Verma, Sudeshna Sinha
We study the dynamics of a ring of patches with vegetation-prey-predator populations, coupled through interactions of the Lotka-Volterra type. We find that the system yields aperio…
Explosive death in nonlinear oscillators coupled by quorum sensing
Umesh Kumar Verma, Sudhanshu Shekhar Chaurasia, Sudeshna Sinha
Many biological and chemical systems exhibit collective behavior in response to the change in their population density. These elements or cells communicate with each other via dyna…
