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…
Smallest chimeras under repulsive interactions
Suman Saha, Syamal Kumar Dana
We present an exemplary system of three identical oscillators in a ring interacting repulsively to show up chimera patterns. The dynamics of individual oscillators is governed by t…
Mitigating long transient time in deterministic systems by resetting
Arnob Ray, Arnab Pal, Dibakar Ghosh +2
How long does a trajectory take to reach a stable equilibrium point in the basin of attraction of a dynamical system? This is a question of quite general interest, and has stimulat…
Emergence of mixed mode oscillations in random networks of diverse excitable neurons: the role of neighbors and electrical coupling
Subrata Ghosh, Argha Mondal, Peng Ji +4
In this paper, we focus on the emergence of diverse neuronal oscillations arising in a mixed population of neurons with different excitability properties. These properties produce…
Extreme events in a network of heterogeneous Josephson junctions
Arnob Ray, Arindam Mishra, Dibakar Ghosh +3
We report rare and recurrent large spiking events in a heterogeneous network of superconducting Josephson junctions (JJ) connected through a resistive load and driven by a radio-fr…
Coupling conditions for globally stable and robust synchrony of chaotic systems
Suman Saha, Arindam Mishra, E. Padmanaban +4
We propose a set of general coupling conditions to select a coupling profile (a set of coupling matrices) from the linear flow matrix (LFM) of dynamical systems for realizing globa…
