Compressibility of dense nuclear matter in the ρ-meson variant of the Skyrme model
Journal of High Energy PhysicsWe 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.

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions
Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Quantization of Skyrmions [PDF]
, 2006 The Skyrme model is a nonlinear classical field theory which models the strong interaction between atomic nuclei. In order to compare the predictions of the Skyrme model with nuclear physics, it has to be quantized. We show, summarizing earlier work, how

, 2015 In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two B=1 Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles.

Coulomb effects in low- and medium-energy heavy-ion collisions
Physics Letters B, 2022 We systematically explore the relative impact of the Coulomb interaction and the nuclear symmetry energy on the proton and neutron density distributions in the 212Pb + 208Pb, 132Sn + 124Sn and 54Ca + 48Ca central collisions at beam energies below 800 MeV/

The deformation of the interacting nucleon in the Skyrme model [PDF]
Physics Letters B, 1996 Changes in the nucleon shape are investigated by letting the nucleon deform under the strong interactions with another nucleon. The parameters of the axial deformations are obtained by minimizing the static energy of the two nucleon system at each internucleon distance $ R $.

Lattices of Generalized Skyrmions [PDF]
, 2011 Generalized Skyrme systems are those which include both the Skyrme and the Skyrme-Faddeev models through an interpolating parameter \alpha \in [0,1] the former corresponds to \alpha=0 and the latter to \alpha=1.

Shape evolution of Ne isotopes and Ne hypernuclei: The interplay of pairing and tensor interactions
EPJ Web of Conferences, 2014 We study tensor and pairing effects on the quadruple deformation of neon isotopes based on a deformed Skyrme-Hartree-Fock model with BCS approximation for the pairing channel. We extend the Skyrme-Hartree-Fock formalism for the description of hypernuclei

The competition of tensor interaction and neutron-proton pairing in the beta-decay of the neutron-rich isotopes [PDF]
EPJ Web of Conferences, 2019 The effects of the residual interaction in the particle-particle channel on β-decay characteristics and the multi-neutron emission probabilities in the β-decay of 126,128,130,132Cd are studied within the quasiparticle random phase approximation with the ...
