The skyrmion-skyrmion interaction
Nuclear Physics A, 1985Using the Skyrme effective lagrangian, baryons emerge as topological solitons. This effective lagrangian is used in adiabatic calculations aimed at providing an essentially parameter-free model of the interaction between such solitons. The resulting skyrmion-skyrmion interaction can be understood as terms simulating the exchange of π-, ρ-, and ω-mesons

Deformation effects in the Skyrmion-Skyrmion interaction
Physical Review D, 1985In the framework of the Skyrme model we calculate the Skyrmion-Skyrmion interaction allowing for deformations in the chiral field. Significant changes in the potentials compared to the ones with the pure hedgehog ansatz appear. This strongly suggests that no convincing calculation of the static N-N potential as constructed from the Skyrmion-Skyrmion ...

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 ...

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

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 ...
