Effects of Janus Oscillators in the Kuramoto Model with Positive and Negative Couplings
Jungzae Choi, MooYoung Choi, Byung-Gook Yoon
We study the effects of Janus oscillators in a system of phase oscillators in which the coupling constants take both positive and negative values. Janus oscillators may also form a…
Traveling Speed of Clusters in the Kuramoto-Sakaguchi Model
Jungzae Choi, MooYoung Choi, Byung-Gook Yoon
We study a variant of Kuramoto-Sakaguchi model in which oscillators are divided into two groups, each characterized by its coupling constant and phase lag. Specifically, we conside…
Interaction Effects on the Size Distribution in a Growth Model
Jungzae Choi, M. Y. Choi, Byung-Gook Yoon
We study, both analytically and numerically, the interaction effects on the skewness of the size distribution of elements in a growth model. We incorporate two types of global inte…
Time Evolution of Entropy in a Growth model: Dependence on the Description
Segun Goh, Jungzae Choi, MooYoung Choi +1
Entropy plays a key role in statistical physics of complex systems, which in general exhibit diverse aspects of emergence on different scales. However, it still remains not fully r…
Traveling cluster pairs in a system of phase oscillators with positive and negative couplings under a periodic driving field
Jungzae Choi, M. Y. Choi, Moon Sung Chung +1
We investigate numerically the clustering behavior of a system of phase oscillators with positive and negative couplings under a periodic external driving field with a bimodal dist…
On the dynamics of traveling phase-oscillators with positive and negative couplings
J. Choi, M. Y. Choi, B. -G. Yoon
We investigate numerically the dynamics of traveling clusters in systems of phase oscillators, some of which possess positive couplings and others negative couplings. The phase dis…
