Complexified Synchrony
Seungjae Lee, Lucas Braun, Frieder Bönisch +3
The Kuramoto model and its generalizations have been broadly employed to characterize and mechanistically understand various collective dynamical phenomena, especially the emergenc…
Volcano Transition in a System of Generalized Kuramoto Oscillators with Random Frustrated Interactions
Seungjae Lee, Yeonsu Jeong, Seung-Woo Son +1
In a system of heterogeneous (Abelian) Kuramoto oscillators with random or `frustrated' interactions, transitions from states of incoherence to partial synchronization were observe…
Chimera Dynamics of Generalized Kuramoto-Sakaguchi Oscillators in Two-population Networks
Seungjae Lee, Katharina Krischer
Chimera dynamics is characterized by the coexistence of coherence and incoherence, arising from a symmetry-breaking mechanism. Extensive research has been performed in various syst…
Heteroclinic Switching between Chimeras in a Ring of Six Oscillator Populations
Seungjae Lee, Katharina Krischer
In a network of coupled oscillators, a symmetry-broken dynamical state characterized by the coexistence of coherent and incoherent parts can spontaneously form. It is known as a ch…
Chaotic Chimera Attractors in a Triangular Network of Identical Oscillators
Seungjae Lee, Katharina Krischer
A prominent type of collective dynamics in networks of coupled oscillators is the coexistence of coherently and incoherently oscillating domains, known as chimera states. Chimera s…
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…
Attracting Poisson Chimeras in Two-population Networks
Seungjae Lee, Katharina Krischer
Chimera states, i.e., dynamical states composed of coexisting synchronous and asynchronous oscillations, have been reported to exist in diverse topologies of oscillators in simulat…
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…
