Theoretical physics deals with physical models. The main requirements for a good physical
model are simplicity and universality. Universal models which can be applied to describe a …

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 …

Characteristic velocities of the electromagnetic waves propagating in vertically stacked
Josephson transmission are theoretically discussed. An equation for solving n velocities of …

We determine the linearised stability of travelling front solutions of a perturbed sine-Gordon
equation. This equation models the long Josephson junction using the RCSJ model for …

In this article, we address the nonlinear localized modes for waveguide arrays with parity-
time (PT)-symmetry characterized by the balanced gain and loss parameters. To investigate …

The dynamics of magnetic fluxons in a system of two vertically stacked long Josephson
junctions is investigated numerically. The model is based on the approach by S. Sakai, P …

We investigate a field-theoretical model that describes the interaction between kinks and
antikinks and between kinks and other heterogeneous fields and impurities. We show that …

We report a method of using a distributed Josephson junction to generate and amplify
electromagnetic waves, based on Cherenkov radiation of linear waves by Josephson …

The article presents the systematic study of the stacked long Josephson junctions in
presence of different magnetic inductances. The coupled sine–Gordon equation along with …

A new model for magnetic coupling between long Josephson junctions is proposed. The
coupling mechanism is a result of the magnetic fields outside the junctions and is …
