Complex dynamics generated by negative and positive feedback delays of a prey-predator system with prey refuge: Hopf bifurcation to Chaos
Debaldev Jana, R. Gopal, M. Lakshmanan
Various field and laboratory experiments show that prey refuge plays a significant role in the stability of prey-predator dynamics. On the other hand, theoretical studies show that…
Phase-flip chimera induced by environmental nonlocal coupling
V. K. Chandrasekar, R. Gopal, D. V. Senthilkumar +1
We report the emergence of a collective dynamical state, namely phase-flip chimera, from an en- semble of identical nonlinear oscillators that are coupled indirectly via the dynami…
Mechanism for intensity induced chimera states in globally coupled oscillators
V. K. Chandrasekar, R. Gopal, A. Venkatesan +1
We identify the mechanism behind the existence of intensity induced chimera states in globally coupled oscillators. We find that the effect of intensity in the system is to cause m…
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…
