Breathing chimera states from purely triadic interactions
Sudo Yi, Gugyoung Kim, Mi Jin Lee +2
The paper shows that chimera states—coexisting synchronized and desynchronized groups—can emerge solely from triadic (three-way) interactions among identical oscillators, and deriv…
Heterogeneous Network Topology Induces the Widom Line
Cook Hyun Kim, B. Kahng
The Widom line, initially identified as a crossover line between liquid-like and gas-like behavior in water and supercritical fluids, separates these two types of behavior. Here, w…
AI-Driven Stabilization in Power Grids through Controlling Line Admittances
Sangjoon Park, Hoyun Choi, Yongsun Lee +3
The global transition from traditional power plants to renewable energy sources introduces new challenges in grid stability, primarily because inverter-based technologies provide i…
Phase lag enhances synchronization in coupled oscillators with inertia
Sudo Yi, Cook Hyun Kim, Heetae Kim +1
The second-order Kuramoto model with inertia exhibits different dynamical behaviors than the first-order KM without inertia. A central difference is its lower synchronization due t…
Ashkin-Teller model with antiferromagnetic four-spin interactions: Interference effect between two conflicting issues
Cook Hyun Kim, Hoyun Choi, Joonsung Jung +1
Spin systems have emerged as powerful tools for understanding collective phenomena in complex systems. In this work, we investigate the Ashkin--Teller (AT) model on random scale-fr…
Neural Graph Simulator for Complex Systems
Hoyun Choi, Sungyeop Lee, B. Kahng +1
Numerical simulation is a predominant tool for studying the dynamics in complex systems, but large-scale simulations are often intractable due to computational limitations. Here, w…
