Plastic Flow, Voltage Bursts, and Vortex Avalanches in Superconductors
C. J. Olson, C. Reichhardt, J. Groth +2
We use large-scale parallel simulations to compute the motion of superconducting magnetic vortices during avalanches triggered by small field increases. We find that experimentally…
Vortex Plastic Motion in Twinned Superconductors
J. Groth, C. Reichhardt, C. J. Olson +2
We present simulations, without electrodynamical assumptions, of , and , in hard superconductors, for a variety of twin-boundary pinning potential…
Spatio-temporal dynamics and plastic flow of vortices in superconductors with periodic arrays of pinning sites
C. Reichhardt, J. Groth, C. J. Olson +2
We present simulations of flux-gradient-driven superconducting rigid vortices interacting with square and triangular arrays of columnar pinning sites in an increasing external magn…
Vortex Plastic Flow, , Deep in the Bose Glass and Mott-Insulator Regimes
C. Reichhardt, C. J. Olson, J. Groth +2
We present simulations of flux-gradient-driven superconducting vortices interacting with strong columnar pinning defects as an external field is quasi-statically swept from…
Microscopic Derivation of Magnetic Flux Density Profiles, Magnetization Hysteresis Loops, and Critical Currents in Strongly Pinned Superconductors
C. Reichhardt, C. J. Olson, J. Groth +2
We present a microscopic derivation, without electrodynamical assumptions, of , , and , in agreement with experiments on strongly pinned supercondu…
