Solitons in Josephson junctions

Magnetic flux quanta in Josephson junctions, often called fluxons, in many cases behave as solitons. A review of recent experiments and modelling of f luxon dynamics in Josephson circuits is presented. Classic quasi-one-dimens ional junctions, stacked junctions (Josephson superlattices), and discrete Josephson transmission lines (JTLs) are discussed. Applications of fluxon d evices as high-frequency oscillators and digital circuits are also addresse d. Copyright (C) 1998 Elsevier Science B.V. All rights reserved.
