Summary: TEHRAN (FNA)- Scientists have created, for the first time a three-dimensional skyrmion
in a quantum gas.
Their topics include resonant X-ray scattering studies on skyrmions
, imaging and tailoring chiral spin textures using spin-polarized electron microscopy, the formation and stability of individual skyrmions
in confined geometries, novel topological resonant excitations of coupled skyrmions
, and magnetic skyrmion
channels: guided motion in potential wells.
An intriguing example emerging from asymmetric spin-interactions are skyrmion
The tip applied a small current that twisted atoms on the film into a skyrmion
(illustrated, left); reapplying the current erased the nanometer-sized vortex.
By creating a particular texture on this added layer, it may be possible to detect differences in the layer's electrical resistance depending on whether a skyrmion
is present or not in the adjacent layer.
Among the topics are skyrmions
and nuclei, rotational symmetry breaking in baby Skyrme models, noncommutative skyrmions
in quantum Hall ferromagnets, half-skyrmion
theory for high-temperature superconductivity, holographic baryons, and baryon physics in a five-dimensional model of hadrons.
: a twisted future Kirsten von Bergmann and Andr Kubetzka explain the nature of a type of quasiparticle known as a magnetic skyrmion
, which looks promising as a bit for future data-storage technology
Together with the strong forces that lock magnetic fields into the skyrmion
pattern, the result is that the magnetic information encoded by skyrmions
is very robust.
A magnetic skyrmion
is an example of a spin-swirling texture characterized by a topological number that will be explored.
With this ability, We will implement/demonstrate the ultrafast writing and erasing of individual skyrmions
in topological magnets.
Both parts two and three deal extensively with composite pseudo-particles, quantum spin effects, skyrmions
, and quantum spin.
Washington, August 01 (ANI): Physicists have discovered a regular lattice of stable magnetic skyrmions
- radial spiral structures made up of atomic-scale spins - on a surface instead of in bulk materials.
