Common Noise-Induced Group-Level Synchronization Between Uncoupled Groups of Oscillators
Tae-Wook Ko
We investigate group-level synchronization between oscillator groups induced by common noise in the absence of inter-group coupling. Each group receives a common noise shared by al…
Phase Response Curves of Coupled Oscillators
Tae-Wook Ko, Bard Ermentrout
Many real oscillators are coupled to other oscillators and the coupling can affect the response of the oscillators to stimuli. We investigate phase response curves (PRCs) of couple…
Partially Locked States in Coupled Oscillators due to Inhomogeneous Coupling
Tae-Wook Ko, Bard Ermentrout
We investigate coupled identical phase oscillators with scale-free distribution of coupling strength. It is shown that partially locked states can occur due to the inhomogeneity in…
Emergence of Chaotic Itinerancy in Simple Ecological Systems
Pan-Jun Kim, Tae-Wook Ko, Hawoong Jeong +2
Chaotic itinerancy is a universal dynamical concept that describes itinerant motion among many different ordered states through chaotic transition in dynamical systems. Unlike the…
Pattern Formation in a Two-Dimensional Array of Oscillators with Phase-Shifted Coupling
Pan-Jun Kim, Tae-Wook Ko, Hawoong Jeong +1
We investigate the dynamics of a two-dimensional array of oscillators with phase-shifted coupling. Each oscillator is allowed to interact with its neighbors within a finite radius.…
Hexagon Formation as a Compromise Between Squares and Stripes in Vertically Vibrated Granular Layers
Tae-Wook Ko, Seong-Ok Jeong, Hie-Tae Moon
We propose a spatially continuous and temporally discrete model for pattern formation in vertically vibrated granular layers. The grain transfer and the grain mobility transitions…
