Extreme events in a complex network: interplay between degree distribution and repulsive interaction
Arnob Ray, Timo Bröhl, Arindam Mishra +5
The role of topological heterogeneity in the origin of extreme events in a network is investigated here. The dynamics of the oscillators associated with the nodes are assumed to be…
Transition to hyperchaos: Sudden expansion of attractor and intermittent large-amplitude events in dynamical systems
S. Leo Kingston, Tomasz Kapitaniak, Syamal K. Dana
Hyperchaos is distinguished from chaos by the presence of at least two positive Lyapunov exponents instead of just one in dynamical systems. A general scenario is presented here th…
Multimodal distribution of transient time of predator extinction in a three-species food chain
Debarghya Pattanayak, Arindam Mishra, Syamal K. Dana +1
Studies of transient dynamics captures the time history of any dramatic changes in the dynamics of a system. The transient dynamics is investigated here in a classic ecological mod…
Transition to hyperchaos and rare large-intensity pulses in Zeeman laser
S. Leo Kingston, Marek Balcerzak, Syamal K. Dana +1
A discontinuous transition to hyperchaos is observed at discrete critical parameters in the Zeeman laser model for three well known nonlinear sources of instabilities, namely, quas…
