Solitons in Josephson junctions

AV Ustinov - Physica D: Nonlinear Phenomena, 1998 - Elsevier
Magnetic flux quanta in Josephson junctions, often called fluxons, in many cases behave as
solitons. A review of recent experiments and modelling of fluxon dynamics in Josephson …

Two-dimensional resonant modes in stacked Josephson junctions

R Kleiner - Physical Review B, 1994 - APS
In a vertical stack of Josephson junctions, vortices in adjacent junctions are coupled by
screening currents if the electrodes are thinner than the London penetration depth. We …

Cherenkov radiation in coupled long Josephson junctions

E Goldobin, A Wallraff, N Thyssen, AV Ustinov - Physical Review B, 1998 - APS
Evidence for Cherenkov radiation of a Josephson vortex is observed in the system of two
magnetically coupled long Josephson junctions. This radiation leads to resonances which …

Prediction of charge and dipole solitons in DNA molecules based on the behaviour of phosphate bridges as tunnel elements
