Spontaneous fluctuations in a magnetic Fe/Gd skyrmion lattice

Physical Review Research, 2021
Magnetic skyrmions are topological spin textures that exhibit classical or quantum quasiparticle behavior. A substantial amount of research has occurred in this field, both because of their unique electromagnetic properties and potential application for ...

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

Kitaev interaction and proximate higher-order skyrmion crystal in the triangular lattice van der Waals antiferromagnet NiI 2

npj Quantum Materials
Topological spin textures are a spectacular manifestation of the chirality of the magnetic nanostructures protected by topology. Most known skyrmion systems are restricted to a topological charge of one, require an external magnetic field for ...

Crystal-orientation dependence of magnetic domain structures in the skyrmion-hosting magnets MnNiGa

APL Materials, 2018
We explore how crystal orientation affects the magnetic domains in the skyrmion-hosting MnNiGa magnets by Lorentz transmission electron microscopy. As a result, we found that the formation of topological spin textures depended significantly on both the ...

Temperature reconfigurable skyrmionic solitons in cholesteric liquid crystals

Soft Matter, 2023
A novel reversible transformation between torons and cholesteric fingers is demonstrated in a cholesteric twist inversion liquid crystal. The torons are shown to be topologically protected and act as nucleation sites for cholesteric fingers.

Unified Approach to Dense Matter

, 2004
We apply the Skyrme model to dense hadronic matter, which provides a unified approach to high density, valid in the large Nc limit. In our picture, dense hadronic matter is described by the classical soliton configuration with minimum energy for the ...

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate

Laser &Photonics Reviews, EarlyView.
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Phase boundary of nuclear matter in magnetic field

Journal of High Energy Physics
Nuclear matter with a strong magnetic field is prevalent inside neutron stars and heavy-ion collisions. In a sufficiently large magnetic field, the ground state is either a chiral soliton lattice (CSL), an array of solitons of the neutral pion field, or ...

Topological magnetic textures in magnetic topological insulators

Physical Review Research, 2021
The surfaces of intrinsic magnetic topological insulators (TIs) host magnetic moments exchange-coupled to Dirac electrons. We study the magnetic phases arising from tuning the electron density using variational and exact diagonalization approaches.

Sliding dynamics of skyrmion molecular crystals

Journal of Physics: Condensed Matter
Abstract Using both atomistic and particle-based simulations, we investigate the current-driven dynamics of skyrmions on two-dimensional periodic substrates when there are multiple skyrmions per substrate minimum. At zero drive, the system forms pinned skyrmion molecular crystal states consisting of dimers, trimers, or dimer-trimer ...
