Mechanism for intensity-induced chimera states in globally coupled oscillators.

Physical review. E, Statistical, nonlinear, and soft matter physics

Chandrasekar VK, Gopal R, Venkatesan A, Lakshmanan M.
PMID: 25615170
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Dec;90(6):062913. doi: 10.1103/PhysRevE.90.062913. Epub 2014 Dec 18.

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 multistability by increasing the number of fixed points. This in turn...

Effect of asymmetry parameter on the dynamical states of nonlocally coupled nonlinear oscillators.

Physical review. E, Statistical, nonlinear, and soft matter physics

Gopal R, Chandrasekar VK, Senthilkumar DV, Venkatesan A, Lakshmanan M.
PMID: 26172781
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Jun;91(6):062916. doi: 10.1103/PhysRevE.91.062916. Epub 2015 Jun 25.

We show that coexisting domains of coherent and incoherent oscillations can be induced in an ensemble of any identical nonlinear dynamical systems using nonlocal rotational matrix coupling with an asymmetry parameter. Further, a chimera is shown to emerge in...
