Morse theory and the Skyrmion-Skyrmion potential
Physical Review D, 1991We apply the Ljusternik-{hacek S}nirelman theory, a derivative of Morse theory, to the Skyrmion-Skyrmion potential in the two-flavor Skyrme model to look for the existence of new, static, classical solutions in the sector with baryon number two. Concomitantly, we present a systematic method for obtaining an expansion of this potential, in inverse ...

Time-dependent solutions of the SU(2) Skyrme model in the hedgehog approximation are determined for classical pion-nucleon scattering at energies where the amplitude of the pion fluctuating field is large, and analysis in terms of normal modes no longer possible.

Magnetic skyrmions are nanoscale spin configurations that hold promise as information carriers in ultradense memory and logic devices owing to the extremely low spin-polarized currents needed to move them.

Physical Review D, 1996
We examine the effects of treating the linear scale of the Skyrmion as a quantum variable. It is found that when angular momentum also is included, the soliton is stable and there is no need for the artificial quartic term traditionally used. These results involve a careful treatment of the constrained degrees of freedom and the quantization procedure ...

Deformation of magnetic skyrmion due to skyrmion–skyrmion interaction
Chinese Physics BAbstract 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.

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 ...

The structure of the skyrmion-skyrmion interaction
Nuclear Physics A, 1986Abstract 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

Eliminating Skyrmion Hall Effect in Ferromagnetic Skyrmions
Nano LettersSkyrmion 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.

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.
