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…
Environment induced Symmetry Breaking of the Oscillation-Death State
Sudhanshu Shekhar Chaurasia, Manish Yadav, Sudeshna Sinha
We investigate the impact of a common external system, which we call a common environment, on the Oscillator Death (OD) states of a group of Stuart-Landau oscillators. The group of…
Control of Hierarchical Networks by Coupling to an External Chaotic System
Sudhanshu Shekhar Chaurasia, Sudeshna Sinha
We explore the behaviour of chaotic oscillators in hierarchical networks coupled to an external chaotic system whose intrinsic dynamics is dissimilar to the other oscillators in th…
Suppression and Revival of Oscillations through Time-varying Interaction
Sudhanshu Shekhar Chaurasia, Anshul Choudhary, Manish Dev Shrimali +1
We explore the dynamical consequences of switching the coupling form in a system of coupled oscillators. We consider two types of switching, one where the coupling function changes…
Suppression of chaos through coupling to an external chaotic system
Sudhanshu Shekhar Chaurasia, Sudeshna Sinha
We explore the behaviour of an ensemble of chaotic oscillators coupled only to an external chaotic system, whose intrinsic dynamics may be similar or dissimilar to the group. Count…
