Thermal Collapse of a Skyrmion
, 2023 This repository contains data and scripts used in Ref. [1]. There, the thermal collapse of a magnetic skyrmion is explored by computing the time evolution of 100x100 spins in a two-dimensional lattice using the Landau-Lifshitz-Langevin equation.

Nonuniform gyrotropic oscillation of skyrmion in a nanodisk
AIP Advances, 2018 It was predicted that magnetic skyrmions have potential application in the spin nano-oscillators. The oscillation frequency is a key parameter. In this paper, we study the skyrmion relaxation in a FeGe nanodisk and find that the oscillation frequency ...

Logic Device Based on Skyrmion Annihilation
, 2021 Skyrmion-based devices are an attractive candidate for nonvolatile memory and low-power computation. In a real device, however, skyrmions easily annihilate at device edges, which hampers device applications.

Baby skyrmion in two-component holographic superfluids
Journal of High Energy Physics, 2023 In the two-component Ginzburg-Landau theory of superfluidity, a pair of fractional vortices form a composite type of topological defect, usually referred to as a baby skyrmion.

Fluctuations and Pinning for Individually Manipulated Skyrmions
Frontiers in Physics, 2021 We numerically examine the dynamics of individually dragged skyrmions interacting simultaneously with an array of other skyrmions and quenched disorder. For drives just above depinning, we observe a broadband noise signal with a 1/f characteristic, while

Journal of High Energy Physics, 2008 Skyrme chains are topologically-nontrivial solutions of the Skyrme model which are (quasi-)periodic in one spatial direction. We report numerical and analytic investigations which show that such solutions exist. Chains of 1-skyrmions are reasonably well approximated both as parallel vortex-antivortex pairs, and in terms of the holonomy of Yang-Mills ...

Vibrational modes of massive Skyrmions within the rational map ansatz [PDF]
, 2007 In this thesis, we study the vibrational modes of some Skyrmion solutions within the rational map approximation. When the Skyrme field is perturbed around a static solution, the radial and angular vibrations of the field are decoupled; this gives us two ...

Advanced Science, EarlyView.Ni‐intercalated graphene on SiC is achieved through a scalable colloidal nanoparticle deposition route. 2D heterostructures show preserved graphene band structure, stable under ambient conditions, and robust interfacial magnetism. Intercalated 2D Ni represents a promising candidate for next‐generation spintronic devices and is a scalable pathway to ...
