Nontrivial Twisted States in Nonlocally Coupled Stuart-Landau Oscillators
Seungjae Lee, Katharina Krischer
A twisted state is an important yet simple form of collective dynamics in an oscillatory medium. Here, we describe a nontrivial type of twisted state in a system of nonlocally coup…
Stable chimeras of non-locally coupled Kuramoto-Sakaguchi oscillators in a finite array
Seungjae Lee, Young Sul Cho
We consider chimera states of coupled identical phase oscillators where some oscillators are phase synchronized while others are desynchronized. It is known that chimera states of…
Effects of interaction range on the behavior of opinion consensus
Seungjae Lee, Young Sul Cho, Hyunsuk Hong
We have frequently encountered the rapid changes that prevalent opinion of the social community is toppled by a new and opposite opinion against the pre-exiting one. To understand…
Twisted states in low-dimensional hypercubic lattices
Seungjae Lee, Young Sul Cho, Hyunsuk Hong
Twisted states with non-zero winding numbers composed of sinusoidally coupled identical oscillators have been observed in a ring. The phase of each oscillator in these states const…
