1/f spectrum in the information transfer model for mass extinction
B. -G. Yoon, M. S. Chung, M. Y. Choi
We study the information transfer model for biological evolution with several kinds of fitness function. The system is stimulated to volve into a stationary state, depending on the…
Frequency resonance in Josephson-junction arrays under strong driving
Jong Soo Lim, M. Y. Choi, Beom Jun Kim
We study resonance behavior of a two-dimensional fully frustrated Josephson-junction array driven by high alternating currents. The signal-to-noise ratio (SNR) is examined as the f…
Optimal Size of a Complex Network
H. Hong, Beom Jun Kim, M. Y. Choi
We investigate the response behavior of an Ising system, driven by an oscillating field, on a small-world network, with particular attention to the effects of the system size. The…
XY model in small-world networks
Beom Jun Kim, H. Hong, Petter Holme +3
The phase transition in the XY model on one-dimensional small-world networks is investigated by means of Monte-Carlo simulations. It is found that long-range order is present at fi…
Double stochastic resonance peaks in systems with dynamic phase transitions
Beom Jun Kim, Petter Minnhagen, Hyun Jin Kim +2
To probe the connection between the dynamic phase transition and stochastic resonance, we study the mean-field kinetic Ising model and the two-dimensional Josephson-junction array…
