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 …

We investigate the nonparametric, pure ac driven dynamics of nonlinear Klein-Gordon
solitary waves having an internal mode of frequency Ω i. We show that the strongest …

The ac driven sine-Gordon equation is studied analytically and numerically, with the aim of
providing a full description of how soliton solutions behave. To date, there is much …

Directed motion of topological solitons (kinks or antikinks) in the damped and ac-driven
discrete sine-Gordon system is investigated. We show that if the driving field breaks certain …

We have proposed theoretically and confirmed numerically the possibility of controlling
chaotic solitons in damped, driven Frenkel-Kontorova chains subjected to additive bounded …

We study the features on the unzipping process of a modified version of the Peyrard–Bishop–
Dauxois model. We show that the inclusion of a barrier in the on-site potential allows for the …

We study numerically synchronization phenomena of mobile discrete breathers in
dissipative nonlinear lattices periodically forced. When varying the driving intensity, the …

By means of numerical simulations, we demonstrate that an alternating-current (ac) field can
support stably moving collective nonlinear excitations in the form of dislocations (topological …

We propose a one-dimensional array of superconducting quantum interference devices
(SQUIDs) composed of three asymmetrically positioned Josephson junctions to realize a …

In this study, we examine the dynamics of a one-dimensional Frenkel-Kontorova chain
consisting of nanosize clusters (the “particles”) and photochromic molecules (the “bonds”) …
