Migration Flows: Population Scaling and Heavy Tails
Cook Hyun Kim, Sangjoon Park, Seoyoung Jin +1
We show how migration between counties in different cities can explain both the population scaling of mean intercity flows and heavy-tailed intercity net-flow distributions. Densit…

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…

Entropy-Induced Phase Transitions in a Hidden Potts Model
Cook Hyun Kim, D. -S. Lee, B. Kahng
A hidden state in which a spin does not interact with any other spin contributes to the entropy of an interacting spin system. Using the Ginzburg-Landau formalism in the mean-field…
