“…However, discreteness also introduces a number of aspects in fluxon dynamics which have no counterparts in the continuum system. The experimental investigation of discrete JJ arrays is a relevant issue in superconducting electronics because they are the basis of the so-called phase-mode logic [13] and of the rapid single-flux-quantum (RSFQ) circuits [14], for the construction of superconducting quantum interference filters (SQIFs) [15], as well as for developing high-frequency mixers [16], or variable inductors and tunable filters [17].…”

The dynamics of a one-dimensional, highly discrete, linear array of alternating 0− and π− Josephson junctions is studied numerically, under constant bias current at zero magnetic field. The calculated current -voltage characteristics exhibit half-integer and integer zero-field-like steps for even and odd total number of junctions, respectively. Inspection of the instantaneous phases reveals that, in the former case, single π−kink excitations (discrete semi-fluxons) are supported, whose propagation in the array gives rise to the 1/2−step, while in the latter case, a pair of π−kink -π−antikink appears, whose propagation gives rise to the 1−step. When additional 2π−kinks are inserted in the array, they are subjected to fractionalization, transforming themselves into two closely spaced π−kinks. As they propagate in the array along with the single π−kink or the π−kink -π−antikink pair, they give rise to higher half-integer or integer zero-field-like steps, respectively.

This review provides a theoretical basis for understanding the current-phase relation (C⌽R) for the stationary (dc) Josephson effect in various types of superconducting junctions. The authors summarize recent theoretical developments with an emphasis on the fundamental physical mechanisms of the deviations of the C⌽R from the standard sinusoidal form. A new experimental tool for measuring the C⌽R is described and its practical applications are discussed. The method allows one to measure the electrical currents in Josephson junctions with a small coupling energy as compared to the thermal energy. A number of examples illustrate the importance of the C⌽R measurements for both fundamental physics and applications.
