Controlling the helicity of magnetic skyrmions by electrical field in frustrated magnets

New Journal of Physics, 2020
The skyrmions generated by frustration in centrosymmetric structures host extra internal degrees of freedom—vorticity and helicity, resulting in distinctive properties and potential functionality, which are not shared by the skyrmions stemming from the ...

S(3) skyrmions and the rational map ansatz [PDF]

, 2000
This paper discusses multi-skyrmions on the 3-sphere with variable radius L using the rational map ansatz. For baryon number B = 3,...,9 this ansatz produces the lowest energy solutions known so far.

Spinning Skyrmions and the Skyrme parameters [PDF]

, 2005
The traditional approach to fixing the parameters of the Skyrme model requires the energy of a spinning Skyrmion to reproduce the nucleon and delta masses.

Reversible writing/deleting of magnetic skyrmions through hydrogen adsorption/desorption

Nature Communications, 2022
To use skyrmions to store information, an effective method for writing and deleting them is required. Here, Chen et al demonstrate the writing and deleting of skyrmions at room temperature by using hydrogen adsorption to change the magnetic anisotropy of

Electrical manipulation of skyrmions in a chiral magnet

Nature Communications, 2022
There has been much interest in using skyrmions for new approaches to compution, however, creating, deleting and driving skyrmions remains a challenge.

Negative Baryon density and the Folding structure of the B=3 Skyrmion [PDF]

, 2013
The Skyrme model is a non-linear field theory whose solitonic solutions, once quantised, describe atomic nuclei. The classical static soliton solutions, so-called Skyrmions, have interesting symmetries and can only be calculated numerically ...

Finkelstein-Rubinstein constraints for the Skyrme model with pion masses [PDF]

, 2006
The Skyrme model is a classical field theory modelling the strong interaction between atomic nuclei. It has to be quantized in order to compare it to nuclear physics.

Laser-induced topological spin switching in a 2D van der Waals magnet

Nature Communications, 2023
Van der Waals magnetic materials, which maintain their magnetic ordering down to a monolayer have been found to host a variety of spin textures, including topological spin textures such as skyrmions. Here, Khela et al.

A Smörgåsbord of Skyrmions

Journal of High Energy Physics, 2022
Abstract We study static solutions of the standard Skyrme model with a pion mass. Using approximately 105 pseudo-random initial configurations made of single Skyrmions in the non-symmetrized product Ansatz and an automatic detection of repeated solutions, we find 409 local energy minimizers (Skyrmions) of the model with baryon ...

Fermions, Skyrmions and the 3-sphere [PDF]

, 2009
This paper investigates a background charge one Skyrme field chirally coupled to light fermions on the 3-sphere. The Dirac equation for the system commutes with a generalized angular momentum or grand spin.
