Long-time dynamics simulations of large (128×128) two-dimensional arrays of Josephson junctions in a uniformly frustrating external magnetic field are reported. The results demonstrate (i) a noisy transverse voltage response to an applied current, a

Time-resolved shock-wave measurements have often been used to infer microstructural behavior in crystalline solids. We apply this approach to an interpretation of the release-wave response of an aluminum alloy (6061-T6) as it is dynamically unloaded

Recent advances in large-scale atomistic materials simulations

Autor: Timothy C. Germann, P.S. Lomdahl

Publikováno v: Computing in Science & Engineering. 1:10-11, 16

There has been a great leap forward in large scale molecular dynamics simulations due to both the growing availability of massively parallel supercomputers and the algorithmic work on parallel neighbor-list and cell-based MD codes. Simulations involv

Publikováno v: Grønbech-Jensen, N, Lomdahl, P S & Samuelsen, M R 1993, ' Fluxon bunching in supercurrent-coupled Josephson junctions ', Physical Review B, vol. 48, no. 9, pp. 6353-6359 . https://doi.org/10.1103/PhysRevB.48.6353

We investigate analytically and numerically the interaction between fluxons of different Josephson junctions coupled through Cooper-pair tunneling. We find that the supercurrent interaction gives rise to attraction between fluxons regardless of their

Return and collapse of solutions to the nonlinear Schrödinger equation in cylindrical symmetry

Autor: Peter Leth Christiansen, P.S. Lomdahl, Ole Hvilsted Olsen

Publikováno v: Physics Letters A. 78:125-128

Cylindrically symmetric wave solutions to the nonlinear Schrodinger equation localized in a ring are investigated numerically. Outward waves expand towards infinity or reach a maximum size and shrink depending on the energy. Inward waves collapse in
