Defect Motion and Lattice Pinning Barrier in Josephson-Junction Ladders
H. Kang, Jong Soo Lim, J. -Y. Fortin +2
We study motion of domain wall defects in a fully frustrated Josephson-unction ladder system, driven by small applied currents. For small system sizes, the energy barrier E_B to th…
Dynamic model for failures in biological systems
J. Choi, M. Y. Choi, B. -G. Yoon
A dynamic model for failures in biological organisms is proposed and studied both analytically and numerically. Each cell in the organism becomes dead under sufficiently strong str…
Network Marketing on a Small-World Network
Beom Jun Kim, Tackseung Jun, Jeong-Yoo Kim +1
We investigate a dynamic model of network marketing in a small-world network structure artificially constructed similarly to the Watts-Strogatz network model. Different from the tr…
Stability of thermodynamic and dynamical order in a system of globally coupled rotors
J. Choi, M. Y. Choi
A system of globally coupled rotors is studied in a unified framework of microcanonical and canonical ensembles. We consider the Fokker-Planck equation governing the time evolution…
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…
Critical currents for vortex defect motion in superconducting arrays
Jong Soo Lim, M. Y. Choi, Beom Jun Kim +1
We study numerically the motion of vortices in two-dimensional arrays of resistively shunted Josephson junctions. An extra vortex is created in the ground states by introducing nov…
