Swarmalators with thermal noise
Hyunsuk Hong, Kevin P. O'Keeffe, Jae Sung Lee +1
We investigate a population of swarmalators, a mobile version of phase oscillators that both sync in time and swarm through space. We focus on a XY-type model of identical swarmala…
Thermodynamic cost of synchronizing a population of beating cilia
Hyunsuk Hong, Junghyo Jo, Changbong Hyeon +1
Synchronization among arrays of beating cilia is one of the emergent phenomena in biological processes at meso-scopic scales. Strong inter-ciliary couplings modify the natural beat…
Correlated disorder in the Kuramoto model: Effects on phase coherence, finite-size scaling, and dynamic fluctuations
Hyunsuk Hong, Kevin P. O'Keeffe, Steven H. Strogatz
We consider a mean-field model of coupled phase oscillators with quenched disorder in the natural frequencies and coupling strengths. A fraction of oscillators are positively c…
Phase coherence induced by correlated disorder
Hyunsuk Hong, Kevin P. O'Keeffe, Steven H. Strogatz
We consider a mean-field model of coupled phase oscillators with quenched disorder in the coupling strengths and natural frequencies. When these two kinds of disorder are uncorrela…
Winding number excitation detects phase transition in one-dimensional XY model with variable interaction range
Hyunsuk Hong, Beom Jun Kim
We numerically study the critical behavior of the one-dimensional XY model of the size N with variable interaction range L. As expected, the standard local order parameter of the m…
Finite-size scaling, dynamic fluctuations, and hyperscaling relation in the Kuramoto model
Hyunsuk Hong, Hugues Chaté, Lei-Han Tang +1
We revisit the Kuramoto model to explore the finite-size scaling (FSS) of the order parameter and its dynamic fluctuations near the onset of the synchronization transition, paying…
Nature of synchronization transitions in random networks of coupled oscillators
Jaegon Um, Hyunsuk Hong, Hyunggyu Park
We consider a system of phase oscillators with random intrinsic frequencies coupled through sparse random networks, and investigate how the connectivity disorder affects the nature…
Link-disorder fluctuation effects on synchronization in random networks
Hyunsuk Hong, Jaegon Um, Hyunggyu Park
We consider one typical system of oscillators coupled through disordered link configurations in networks, i.e., a finite population of coupled phase oscillators with distributed in…
Rectification of spatial disorder
Jaegon Um, Hyunsuk Hong, Fabio Marchesoni +1
We demonstrate that a large ensemble of noiseless globally coupled-pinned oscillators is capable of rectifying spatial disorder with spontaneous current activated through a dynamic…
Finite-size scaling of synchronized oscillation on complex networks
Hyunsuk Hong, Hyunggyu Park, Lei-Han Tang
The onset of synchronization in a system of random frequency oscillators coupled through a random network is investigated. Using a mean-field approximation, we characterize sample-…
Finite-size scaling in complex networks
Hyunsuk Hong, Meesoon Ha, Hyunggyu Park
A finite-size-scaling (FSS) theory is proposed for various models in complex networks. In particular, we focus on the FSS exponent, which plays a crucial role in analyzing numerica…
Entrainment transition in populations of random frequency oscillators
Hyunsuk Hong, Hugues Chate, Hyunggyu Park +1
The entrainment transition of coupled random frequency oscillators is revisited. The Kuramoto model (global coupling) is shown to exhibit unusual sample-dependent finite size effec…
Anomalous Binder Cumulant and Lack of Self-Averageness in Systems with Quenched Disorder
Hyunsuk Hong, Hyunggyu Park, Lei-Han Tang
The Binder cumulant (BC) has been widely used for locating the phase transition point accurately in systems with thermal noise. In systems with quenched disorder, the BC may show s…

Meesoon Ha, Hyunsuk Hong, Hyunggyu Park
Recently, Castellano and Pastor-Satorras [1] utilized the finite size scaling (FSS) theory to analyze simulation data for the contact process (CP) on scale-free networks (SFNs) and…
Modular synchronization in complex networks
E. Oh, K. Rho, H. Hong +1
We study the synchronization transition (ST) of a modified Kuramoto model on two different types of modular complex networks. It is found that the ST depends on the type of inter-m…
Factors that predict better synchronizability on complex networks
H. Hong, Beom Jun Kim, M. Y. Choi +1
While shorter characteristic path length has in general been believed to enhance synchronizability of a coupled oscillator system on a complex network,the suppressing tendency of t…
