[HTML][HTML] Quantum binding energies in the Skyrme model

SB Gudnason, C Halcrow - Physics Letters B, 2024 - Elsevier
A major problem in the Skyrme model is that the binding energy of skyrmions, which model
nuclei, is too high by an order of magnitude. We show that the most popular solution to this …

[HTML][HTML] Skyrme crystals with massive pions

D Harland, P Leask, M Speight - Journal of Mathematical Physics, 2023 - pubs.aip.org
The crystalline structure of nuclear matter is investigated in the standard Skyrme model with
massive pions. A semi-analytic method is developed to determine local minima of the static …

Skyrmion crystals stabilized by ω-mesons

D Harland, P Leask, M Speight - Journal of High Energy Physics, 2024 - Springer
A bstract We investigate the ground state crystalline structure of nuclear matter in the ω-
meson variant of the Skyrme model. After minimizing energy with respect to variations of …

Compressibility of dense nuclear matter in the ρ-meson variant of the Skyrme model

M Huidobro, P Leask, C Naya… - Journal of High Energy …, 2025 - Springer
A bstract We show that coupling the SU (2)-valued Skyrme field to the ρ-meson solves the
long-standing issue of (in) compressibility in the solitonic Skyrme model. Even by including …

Integral identities and universal relations for solitons

C Adam, AG Martin-Caro, C Naya, A Wereszczyński - Physical Review D, 2024 - APS
We show that any nonlinear field theory giving rise to static solutions with finite energy like,
eg, topological solitons, allows us to derive an infinite number of integral identities which any …

Baby skyrmion crystals stabilized by vector mesons

P Leask - arxiv preprint arxiv:2403.14810, 2024 - arxiv.org
In this letter we study soliton crystals in the $(2+ 1) $-dimensional analogue model of the
$(3+ 1) $-dimensional Adkins--Nappi model of nuclear physics. The baby $\omega …

Domain Wall Networks as Skyrmion Crystals in Chiral Magnets

S Lee, T Fujimori, M Nitta, SK Kim - arxiv preprint arxiv:2407.04007, 2024 - arxiv.org
We theoretically investigate the ground states of a chiral magnet with a square anisotropy
and show that it supports domain wall networks as stable ground states. A domain wall …

Carbon-12 in the generalized Skyrme model

C Adam, C Naya, A Wereszczyński - arxiv preprint arxiv:2401.08778, 2024 - arxiv.org
We study properties of the $^{12} $ C nucleus within the generalized Skyrme model where,
in addition to the standard massive Skyrme model, the sextic term and the pionic potential …

[PDF][PDF] Skyrmion Crystals: Finite Atomic Nuclei to Compact Stars

P Leask - 2024 - etheses.whiterose.ac.uk
In this thesis we study the properties of nuclear matter in the massive ℒ024 and generalized
ℒ0246 Skyrme models, and also the 𝜔-meson variant of the Skyrme model. A semi-analytic …
