Amplitude mediated chimera states
Gautam C Sethia, Abhijit Sen, George L. Johnston
We investigate the possibility of obtaining chimera state solutions of the non-local Complex Ginzburg-Landau Equation (NLCGLE) in the strong coupling limit when it is important to…
Phaselocked patterns and amplitude death in a ring of delay coupled limit cycle oscillators
Ramana Dodla, Abhijit Sen, George L. Johnston
We study the existence and stability of phaselocked patterns and amplitude death states in a closed chain of delay coupled identical limit cycle oscillators that are near a supercr…
Driven response of time delay coupled limit cycle oscillators
D. V. Ramana Reddy, A. Sen, G. L. Johnston
We study the periodic forced response of a system of two limit cycle oscillators that interact with each other via a time delayed coupling. Detailed bifurcation diagrams in the par…
Experimental Evidence of Time Delay Induced Death in Coupled Limit Cycle Oscillators
D. V. Ramana Reddy, A. Sen, G. L. Johnston
Experimental observations of time delay induced amplitude death in a pair of coupled nonlinear electronic circuits that are individually capable of exhibiting limit cycle oscillati…
Dynamics of a Limit Cycle Oscillator under Time Delayed Linear and Nonlinear Feedbacks
D. V. Ramana Reddy, A. Sen, G. L. Johnston
We study the effects of time delayed linear and nonlinear feedbacks on the dynamics of a single Hopf bifurcation oscillator. Our numerical and analytic investigations reveal a host…
Time Delay Effects on Coupled Limit Cycle Oscillators at Hopf Bifurcation
D. V. Ramana Reddy, A. Sen, G. L. Johnston
We present a detailed study of the effect of time delay on the collective dynamics of coupled limit cycle oscillators at Hopf bifurcation. For a simple model consisting of just two…
