Extreme bursting events via pulse-shaped explosion in mixed Rayleigh-Lienard nonlinear oscillator
B. Kaviya, R. Suresh, V. K. Chandrasekar
We study the dynamics of a parametrically and externally driven Rayleigh-Lienard hybrid model and report the emergence of extreme bursting events due to a novel pulse-shaped explos…
Dynamics of coupled modified Rossler oscillators: the role of nonisochronicity parameter
C. Ramya, R. Gopal, R. Suresh +1
The amplitude-dependent frequency of the oscillations, termed \emph{nonisochronicity}, is one of the essential characteristics of nonlinear oscillators. In this paper, the dynamics…
Influence of dissipation on extreme oscillations of a forced anharmonic oscillator
B. Kaviya, R. Suresh, V. K. Chandrasekar +1
Dynamics of a periodically forced anharmonic oscillator (AO) with cubic nonlinearity, linear damping, and nonlinear damping, is studied. To begin with, the authors examine the dyna…
Chimera at the phase-flip transition of an ensemble of identical nonlinear oscillators
R. Gopal, V. K. Chandrasekar, D. V. Senthilkumar +2
A complex collective emerging behavior characterized by coexisting coherent and incoherent do- mains is termed as a chimera state. We bring out the existence of a new type of chime…
Different Types of Synchronization in Coupled Network Based Chaotic Circuits
K. Srinivasan, V. K Chandrasekar, R. Gladwin Pradeep +2
We propose a simple and new unified method to achieve lag, complete and anticipatory synchronizations in coupled nonlinear systems. It can be considered as an alternative to the su…
Different kinds of chimera death states in nonlocally coupled oscillators
K. Premalatha, V. K. Chandrasekar, M. Senthilvelan +1
We investigate the significance of nonisochronicity parameter in a network of nonlocally coupled Stuart-Landau oscillators with symmetry breaking form. We observe that the presence…
Feedback as a mechanism for the resurrection of oscillations from death state
V. K. Chandrasekar, S. Karthiga, M. Lakshmanan
The quenching of oscillations in interacting systems leads to several unwanted situations, which necessitate a suitable remedy to overcome the quenching. In this connection, this w…
Emergence of coexisting coherence and incoherence by an external forcing
V. K. Chandrasekar, R. Suresh, D. V. Senthilkumar +1
A common external forcing can cause a saddle-node bifurcation in an ensemble of identical Duffing oscillators by breaking the symmetry of the individual bistable (double-well) unit…
Effect of asymmetry parameter on the dynamical states of nonlocally coupled nonlinear oscillators
R. Gopal, V. K. Chandrasekar, D. V. Senthilkumar +2
We show that coexisting domains of coherent and incoherent oscillations can be induced in an ensemble of any identical nonlinear dynamical systems using the nonlocal rotational mat…
Enhanced synchronization in an array of spin torque nano oscillators in the presence of oscillating external magnetic field
B. Subash, V. K. Chandrasekar, M. Lakshmanan
We demonstrate that the synchronization of an array of electrically coupled spin torque nano-oscillators (STNO) modelled by Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can…
Observation and characterization of chimera states in coupled dynamical systems with nonlocal coupling
R. Gopal, V. K. Chandrasekar, A. Venkatesan +1
By developing the concepts of strength of incoherence and discontinuity measure, we show that a distinct quantitative characterization of chimera and multichimera states which occu…

B. Subash, V. K. Chandrasekar, M. Lakshmanan
Considering an array of spin torque transfer nano oscillators (STNOs), we have investigated the synchronization property of the system under the action of a common periodically dri…
