Two levels of topology in skyrmion lattice dynamics

Physical Review Research
Skyrmions are localized, topological spin structures that can be described as quasiparticles. Skyrmions in thin films are an ideal model system to study Brownian motion and lattice formation in two dimensions.

Skyrmions in square-lattice antiferromagnets

, 2016
The ground states of square-lattice two-dimensional antiferromagnets with anisotropy in an external magnetic field are determined using Monte Carlo simulations and compared to theoretical analysis.

Hybrid magnetic skyrmions with near-zero Hall angle and electrical switchability in a 2D multiferroic

npj Computational Materials
Magnetic skyrmions hold great promise as information carriers in spintronics, yet their practical implementation is impeded by the skyrmion Hall effect (SkHE).

Fermionic domain-wall Skyrmions of QCD in a magnetic field

Journal of High Energy Physics
The ground state of low-energy QCD matter in strong magnetic fields is either a chiral soliton lattice (CSL), a periodic array of neutral pion domain walls (chiral solitons) perpendicular to the magnetic field, or domain-wall Skyrmion phase, in which ...

JNR Skyrmions

Journal of High Energy Physics
Abstract The JNR ansatz provides a simple formula to obtain families of charge N self-dual SU(2) Yang-Mills instantons in four-dimensional Euclidean space, from the free data of N + 1 distinct points with associated positive weights.

The quantum nature of skyrmions and half-skyrmions in Cu2OSeO3

, 2014
The Skyrme-particle, the skyrmion, was introduced over half a century ago in the context of dense nuclear matter. But with skyrmions being mathematical objects -special types of topological solitons -they can emerge in much broader contexts.
