Adding crust to BPS Skyrme neutron stars
- PhysicsPhysical Review D
- 2020
The Skyrme model and its generalisations provide a conceptually appealing field-theory basis for the description of nuclear matter and, after its coupling to gravity, also of neutron stars. In…
BPS Skyrme neutron stars in generalized gravity
- PhysicsJournal of Cosmology and Astroparticle Physics
- 2020
We study the coupling of nuclear matter described by the BPS Skyrme model to generalized gravity. Concretely, we consider the Starobinsky model which provides the leading-order correction to the…
Neutron stars within the Skyrme model
- PhysicsInternational Journal of Modern Physics E
- 2019
The Skyrme model is a low energy effective field theory of strong interactions where nuclei and baryons appear as collective excitations of pionic degrees of freedom. In the last years, there has…
A false vacuum Skyrme model for nuclear matter
- PhysicsJournal of Physics G: Nuclear and Particle Physics
- 2022
The low energy regime of Quantum Chromodynamics (QCD) presents enormous challenges due to its large coupling. Effective field theories, like the Skyrme model, are useful approaches to study…
Baryon chemical potential and in-medium properties of BPS skyrmions
- Physics
- 2015
We continue the investigation of thermodynamical properties of the Bogomol'nyi-Prasad-Sommerfield (BPS) Skyrme model. In particular, we analytically compute the baryon chemical potential both in the…
Quasiuniversal relations for generalized Skyrme stars
- PhysicsPhysical Review D
- 2021
First proposed in 2013 by Yagi and Yunes, the quasi-universal \emph{I-Love-Q relations} consist of a set of relations between the moment of inertia, the spin-induced quadrupole moment and the…
BPS sectors of the Skyrme model and their non-BPS extensions
- Physics
- 2017
Two recently found coupled Bogomol’nyi-Prasad-Sommerfield (BPS) submodels of the Skyrme model are further analyzed. First, we provide a geometrical formulation of the submodels in terms of the…

Slowly rotating anisotropic neutron stars in general relativity and scalar–tensor theory
- Physics
- 2014
Some models (such as the Skyrme model, a low-energy effective field theory for quantum chromodynamics) suggest that the high-density matter prevailing in neutron star (NS) interiors may be…
Gravitating gauged BPS baby Skyrmions
- PhysicsPhysical Review D
- 2019
We show that the minimally gauged BPS baby Skyrme model remains a BPS theory after coupling with gravity that is the topologically nontrivial configurations called baby Skyrmions carrying magnetic…

Near-BPS Skyrmions: Non-shell configurations and Coulomb effects
- Physics
- 2012
The relatively small binding energy in nuclei suggests that they may be well represented by near-BPS Skyrmions since their mass is roughly proportional to the baryon number $A.$ For that purpose, we…
Nuclear binding energies from a Bogomol'nyi-Prasad-Sommerfield Skyrme model
- Physics
- 2013
Recently, within the space of generalized Skyrme models, a submodel with a Bogomol'nyi-Prasad-Sommerfield (BPS) bound was identified that reproduces some bulk properties of nuclear matter already on…
Phase Transition and Anisotropic Deformations of Neutron Star Matter
- Physics, Geology
- 2012
The Skyrme model is a low energy, effective field theory for QCD which when coupled to a gravitational field provides an ideal semi-classical model to describe neutron stars. We use the Skyrme…
Light Nuclei of Even Mass Number in the Skyrme Model
- Physics

We consider the semiclassical rigid-body quantization of Skyrmion solutions of mass numbers $B=4,6,8,10$, and 12. We determine the allowed quantum states for each Skyrmion and find that they often…
Skyrmions, instantons and holography
- Physics

Some time ago, Atiyah and Manton observed that computing the holonomy of Yang-Mills instantons yields good approximations to static Skyrmion solutions of the Skyrme model. This paper provides an…
Skyrmions in a truncated BPS theory

Recently, it has been shown that (4 + 1)-dimensional Yang-Mills theory may be written as a (3 + 1)-dimensional BPS Skyrme model, in which the Skyrme field is coupled toan infinite tower of vector…
Thermodynamics of the BPS Skyrme model
- Physics
- 2014
One problem in the application of the Skyrme model to nuclear physics is that it predicts too large a value for the compression modulus of nuclear matter. Here we investigate the thermodynamics of…
