Abstract
In this article we consider the influence of a periodic sequence of Gaussian
pulses on a chimera state in a ring of coupled FitzHugh-Nagumo systems. We
found that on the way to complete spatial synchronization one can observe a
number of variations of chimera states that are not typical for the parameter
range under consideration. For example, the following modes were found:
breathing chimera, chimera with intermittency in the incoherent part, traveling
chimera with strong intermittency, and others. For comparison, here we also
consider the impact of a harmonic influence on the same chimera, and to
preserve the generality of the conclusions, we compare the regimes caused by
both a purely positive harmonic influence and a positive-negative one.
