Discrete localized modes supported by an inhomogeneous defocusing nonlinearity

, 2013
We report that infinite and semi-infinite lattices with spatially inhomogeneous self-defocusing (SDF)\ onsite nonlinearity, whose strength increases rapidly enough toward the lattice periphery, support stable unstaggered (UnST) discrete bright solitons ...

Moving Bragg grating solitons in a semilinear dual-core system with dispersive reflectivity

Scientific Reports, 2017
The existence, stability and collision dynamics of moving Bragg grating solitons in a semilinear dual-core system where one core has the Kerr nonlinearity and is equipped with a Bragg grating with dispersive reflectivity, and the other core is linear are

Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

Heat Transfer, EarlyView.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

Soliton collisions in soft magnetic nanotube with uniaxial anisotropy

AIP Advances, 2016
The structure of stable magnetic solitons of various orders in soft magnetic nanotube with uniaxial magnetic anisotropy has been studied using numerical simulation. Solitons of even order are immobile in axially applied magnetic field.

Bright solitons and soliton trains in a fermion-fermion mixture

, 2006
We use a time-dependent dynamical mean-field-hydrodynamic model to predict and study bright solitons in a degenerate fermion-fermion mixture in a quasi-one-dimensional cigar-shaped geometry using variational and numerical methods.

Temperature‐robust exchange bias and spin‐orbit torque switching in van der Waals heterostructure

InfoMat, EarlyView.
Exchange bias (EB) in ferromagnetic/antiferromagnetic materials enables high‐density spintronic devices. A Fe3GaTe2/NiPS3 heterostructure exhibits EB up to 150 K, with spin orbit torque switching observed in both stacking orders. Interface layer effects induce net magnetism and magnetization flipping via Fe3GaTe2 domains, with strong interlayer ...

Topological Solitons

, 2004
Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons.
