Hydrodynamics of local excitations after an interaction quench in 1D cold atomic gases

open access: yesNew Journal of Physics, 2016
We discuss the hydrodynamic approach to the study of the time evolution—induced by a quench—of local excitations in one dimension. We focus on interaction quenches: the considered protocol consists of creating a stable localized excitation propagating ...

Spin dynamics in helical molecules with nonlinear interactions

open access: yesNew Journal of Physics, 2018
It is widely admitted that the helical conformation of certain chiral molecules may induce a sizable spin selectivity observed in experiments. Spin selectivity arises as a result of the interplay between a helicity-induced spin–orbit coupling (SOC) and ...

Comment on ``Magnon wave forms in the presence of a soliton in two--dimensional antiferromagnets with a staggered field''

open access: yes, 2006
Very recently Fonseca and Pires [Phys. Rev. B 73, 012403(2006)] have studied the soliton--magnon scattering for the isotropic antiferromagnet and calculated ``exact'' phase shifts, which were compared with the ones obtained by the Born approximation.

Numerical study on diverging probability density function of flat-top solitons in an extended Korteweg-de Vries equation [PDF]

open access: yes, 2009
We consider an extended Korteweg-de Vries (eKdV) equation, the usual Korteweg-de Vries equation with inclusion of an additional cubic nonlinearity. We investigate the statistical behaviour of flat-top solitary waves described by an eKdV equation in the ...

Three-dimensional hybrid vortex solitons

open access: yesNew Journal of Physics, 2014
We show, by means of numerical and analytical methods, that media with a repulsive nonlinearity which grows from the center to the periphery support a remarkable variety of previously unknown complex stationary and dynamical three-dimensional (3D ...

Utmost travelling wave phenomena to the fractional type nonlinear evolution equation in mathematical physics

open access: yesPartial Differential Equations in Applied Mathematics
In applied physics and engineering, non-linear fractional types of partial differential equations become increasingly prominent as an estimation technique to explain a wide variety of non-linear phenomena.

Computational methods and traveling wave solutions for the fourth-order nonlinear Ablowitz-Kaup-Newell-Segur water wave dynamical equation via two methods and its applications

open access: yesOpen Physics, 2018
The aim of this article is to construct some new traveling wave solutions and investigate localized structures for fourth-order nonlinear Ablowitz-Kaup-Newell-Segur (AKNS) water wave dynamical equation.

Large-amplitude electron-acoustic solitons in a dusty plasma with kappa-distributed electrons

open access: yes, 2011
The Sagdeev pseudopotential method is used to investigate the occurrence and the dynamics of fully nonlinear electrostatic solitary structures in a plasma containing suprathermal hot electrons, in the presence of massive charged dust particles in the ...

Are the low-momentum gluon correlations semiclassically determined? [PDF]

open access: yes, 2004
We argue that low-energy gluodynamics can be explained in terms of semi-classical Yang-Mills solutions by demonstrating that lattice gluon correlation functions fit to instanton liquid predictions for low energies and, after cooling, in the whole range ...

Nonlinear self adjointness, conservation laws and exact solutions of ill-posed Boussinesq equation

open access: yesOpen Physics, 2016
In this work, we consider the ill-posed Boussinesq equation which arises in shallow water waves and non-linear lattices. We prove that the ill-posed Boussinesq equation is nonlinearly self-adjoint.
