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…
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…
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…
