The Anti-FPU Problem

open access: yes, 2004
We present a detailed analysis of the modulational instability of the zone-boundary mode for one and higher-dimensional Fermi-Pasta-Ulam (FPU) lattices.

Dynamics of semifluxons in Nb long Josephson 0-pi junctions

open access: yes, 2003
We propose, implement and test experimentally long Josephson 0-pi junctions fabricated using conventional Nb-AlOx-Nb technology. We show that using a pair of current injectors, one can create an arbitrary discontinuity of the Josephson phase and in ...

Physarum machines for space missions [PDF]

open access: yes, 2013
A Physarum machine is a programmable amorphous biological computer experimentally implemented in plasmodium Physarum polycephalum. We overview a range of tasks solvable by Physarum machines and speculate on how the Physarum machines could be used in ...

Magnetic lump motion in saturated ferromagnetic films

open access: yes, 2023
In this paper, we study in detail the nonlinear propagation of magnetic soliton in a ferromagnetic film. The sample is magnetized to saturation by an external field perpendicular to film plane.

Emergence of collapsed snaking related dark and bright Kerr dissipative solitons with quartic-quadratic dispersion

open access: yes, 2023
We theoretically investigate the dynamics, bifurcation structure and stability of dark localized states emerging in Kerr cavities in the presence of second- and fourth-order dispersion.

Space-time observation of the dynamics of soliton collisions in a recirculating optical fiber loop

open access: yes, 2023
We present experiments performed in a recirculating fiber loop in which we realize the single-shot observation of the space and time interaction of two and three bright solitons. The space-time evolutions observed in experiments provide clear evidence of

Amplification of matter rogue waves and breathers in quasi-two-dimensional Bose-Einstein condensates

open access: yes, 2016
We construct rogue wave and breather solutions of a quasi-two-dimensional Gross-Pitaevskii equation with a time-dependent interatomic interaction and external trap. We show that the trapping potential and an arbitrary functional parameter that present in

Exploring the Dynamics of Nonlocal Nonlinear Waves: Analytical Insights into the Extended Kadomtsev-Petviashvili Model

open access: yes, 2023
The study of nonlocal nonlinear systems and their dynamics is a rapidly increasing field of research. In this study, we take a closer look at the extended nonlocal Kadomtsev-Petviashvili (enKP) model through a systematic analysis of explicit solutions ...

Rogue Waves in Ultracold Bosonic Seas [PDF]

open access: yes, 2018
In this work, we numerically consider the initial value problem for nonlinear Schrodinger (NLS)-type models arising in the physics of ultracold bosonic gases, with generic Gaussian wavepacket initial data.

An application of the Maslov complex germ method to the 1D nonlocal Fisher-KPP equation

open access: yes, 2018
A semiclassical approximation approach based on the Maslov complex germ method is considered in detail for the 1D nonlocal Fisher-Kolmogorov-Petrovskii-Piskunov equation under the supposition of weak diffusion.
