An overview of the dynamics of one of the fundamental models of low-dimensional nonlinear
physics, the Frenkel–Kontorova (FK) model, is presented. In its simplest form, the FK model …

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 …

Coherent and continuous radiation sources of the electromagnetic (EM) waves at terahertz
(1 THz= 10 12 c/s) frequencies using a mesa structure fabricated from high temperature …

In some practical applications, devices based on superconducting electronics, due to their
unique set of parameters, are far superior to those based on conventional technologies …

Flux-flow oscillators (FFO's) are being developed for integration with a SIS mixer for use in
submillimeter wave receivers. The present work contains a detailed experimental study of …

We report the observation of the ratchet effect for a relativistic flux quantum trapped in an
annular Josephson junction embedded in an inhomogeneous magnetic field. In such a solid …

We have considered relativistic soliton dynamics governed by the sine-Gordon equation and
affected by short spatial inhomogeneities of the driving force and thermal noise. Developed …

We describe the readout process of the state of a Josephson flux qubit via solitons in
Josephson transmission lines (JTLs) as they are in use in the standard rapid single flux …

The nucleation rate of interacting thermal kinks and antikinks in a sine-Gordon chain is
evaluated within the dilute-gas approximation. Our novel result describes both the diffusive …
