3D Topological Toron‐Like Domains in Magnetic Nanoparticles: A Micromagnetic Simulation
Advanced Physics Research, EarlyView.This study systematically investigates the size‐dependent behaviors of non‐uniform magnetic domain structures in submicron‐sized FeNi nanoparticles using micromagnetic simulations. The existence of magnetic toron‐like structures at the submicron scale is identified.

Modulational Instability and Dynamical Growth Blockade in the Nonlinear Hatano–Nelson Model
Advanced Physics Research, EarlyView.The nonlinear Hatano–Nelson model under periodic boundary conditions is investigated, revealing a novel growth blockade phenomenon triggered by the modulational instability of nonlinear plane waves. This effect, characterized by the abrupt halt of norm growth, arises from self‐induced disorder, marking a departure from the convective motion observed in

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 107-142, January 2023., 2023 In this article, a novel mass and momentum conservative semi‐implicit finite volume scheme is developed for the coupled solution of hydrostatic shallow water flow and the movement of one or more floating rigid bodies. The coupling is achieved via a nonlinear volume function in the mass conservation equation that depends on the coordinates of the ...

Altermagnetism in NiSi and Antiferromagnetic Candidate Materials with Non‐Collinear Spins
Advanced Physics Research, EarlyView.Altermagnetism has emerged as new class of phenomena in magnetic materials. But experimental evidences to the theoretically proposed concept is still scarce. That's because the research is mostly focused on collinear antiferromagnets and ignoring the vast landscape rendered by non‐collinear spin correlation.

Nonlinear impedance matching control for a submerged wave energy converter
IET Control Theory & ApplicationsThe impedance matching control, also known as approximate complex conjugate control (ACC), is one of the main strategies for improving the capture of energy by point absorber wave energy converters. Such a strategy shapes the mechanical impedance related

Mechanical Spin Waves in a Nonlocal Discrete Magnetoelastic Lattice with Negative Group Velocity
Advanced Physics Research, EarlyView.A discrete magnetoelastic lattice enables mechanical spin waves. The zigzag‐arranged lattice consists of repulsive magnets. The top and bottom rows of the zigzag lattice show opposite spin directions. These spin waves arise due to the coupling between longitudinal and transverse motions.

Existence of attractors for the non-autonomous Berger equation with nonlinear damping
Electronic Journal of Differential Equations, 2017 In this article, we study the long-time behavior of the non-autonomous Berger equation with nonlinear damping. We prove the existence of a compact uniform attractor for the Berger equation with nonlinear damping in the space $(H^2(\Omega)\cap H_0^1 ...
