Skyrmion-based artificial synapses for neuromorphic computing

Nature Electronics, 2019
Magnetic skyrmions are topologically protected spin textures that have nanoscale dimensions and can be manipulated by an electric current. These properties make the structures potential information carriers in data storage, processing and transmission ...

Quantization of the Skyrmion

Physical Review D, 1993
We apply the Kerman-Klein method of quantization, an approach based on Heisenberg matrix mechanics, to the Skyrme model. In this approach the operator equations of motion and kinematical constraints are evaluated within an appropriately chosen Hilbert space, and the resulting set of c-number equations is solved to determine the values of matrix ...

Direct observation of the skyrmion Hall effect

Nature Physics, 2016
The well-known Hall effect describes the transverse deflection of charged particles (electrons/holes) as a result of the Lorentz force. Similarly, it is intriguing to examine if quasi-particles without an electric charge, but with a topological charge ...

Masses of Skyrmions

Physical Review D, 1989
Quand ils sont suffisamment realistes pour la description des mesons, les lagrangiens effectifs de type Skyrme, proposes anterieurement, predisent des masses qui sont trop elevees pour le nucleon. On essaie de resoudre ce probleme en etudiant les effets du terme quantique, origine par le meson θ(J pc =0 ++ , I=0).

Deformation of magnetic skyrmion due to skyrmion–skyrmion interaction

Chinese Physics B
Abstract Understanding skyrmion–skyrmion interactions and their dynamical effects is crucial for skyrmion-based applications. In this article, we investigate the deformation of skyrmions induced by the inter-skyrmion interaction in both static and dynamic scenarios for a two-skyrmion system.

The structure of the skyrmion-skyrmion interaction

Nuclear Physics A, 1986
Abstract The structure of the skyrmion-skyrmion interaction is investigated. Using a zero-range boson-exchange interpretation, Skyrme models can be related to models including explicit boson stabilization. The structure of the potential can be understood in terms of conventional boson-exchange pictures and corrections to the conventional Skyrme model

Skyrmions

2017
An important application of spin dynamics is the response of a magnetic material subjected to an external stimuli. In the previous chapter we discussed the response of primarily ferromagnets to temperature fluctuations that manifest itself to spin excitations and magnons.

Eliminating Skyrmion Hall Effect in Ferromagnetic Skyrmions

Nano Letters
Skyrmion Hall effect (SkHE) remains an obstacle for the application of magnetic skyrmions. While methods have been established to cancel or compensate SkHE in artificial antiferromagnets and ferrimagnets, eliminating intrinsic SkHE in ferromagnets is still a big challenge.
