Advanced Materials, EarlyView.Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

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.

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

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 ...

Reconfigurable Spoof Plasmonic Skyrmion Electronics for Deformation‐Invariant Multimode Sensing
Advanced Science, EarlyView.A flexible multimode sensor based on capacitively loaded spoof plasmonic skyrmions enables deformation‐invariant dielectric sensing with ultra‐compact size and high Q‐factor. Near‐equidistant resonances remain stable under shape change and bending, while capacitor loading improves bending robustness and multimode sensitivity, highlighting strong ...

Skyrmion size in skyrmion crystals
, 2021 A magnetic skyrmion is a topological object that can exist as a solitary embedded in the vast ferromagnetic phase, or coexists with a group of its "siblings" in various stripy phases as well as skyrmion crystals (SkXs). Isolated skyrmions and skyrmions in an SkX are circular while a skyrmion in other phases is a stripe of various forms.
