Size of flux jumps in superconducting films
D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +2
Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a…
Avalanche-driven fractal flux distributions in NbN superconducting films
I. A. Rudnev, D. V. Shantsev, T. H. Johansen +1
Flux distributions in thin superconducting NbN films placed in a perpendicular magnetic field have been studied using magneto-optical imaging. Below 5.5 K the flux penetrates in th…
Low-frequency noise as a source of dephasing of a qubit
Y. M. Galperin, B. L. Altshuler, D. V. Shantsev
With the growing efforts in isolating solid-state qubits from external decoherence sources, the material-inherent sources of noise start to play crucial role. One representative ex…
Magnetostrictive behaviour of thin superconducting disks
Tom H. Johansen, Daniel V. Shantsev
Flux-pinning-induced stress and strain distributions in a thin disk superconductor in a perpendicular magnetic field is analyzed. We calculate the body forces, solve the magneto-el…
Comparison of flux creep an nonlinear E-j approach for analysis of vortex motion in superconductors
D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +1
Two commonly accepted approaches for simulations of thermally-activated vortex motion in superconductors are compared. These are (i) the so-called flux creep approach based on the…
