A bstractRadial vibrations of charge one hedgehog Skyrmions in the full Skyrme model are analysed. We investigate how the properties of the lowest resonance modes (quasi normal modes) — their frequencies and widths — depend on the form of the potential (value of the pion mass as well as the addition of further potentials) and on the inclusion of the sextic term. Then we consider the inverse problem, where certain values for the frequencies and widths are imposed, and the field theoretic Skyrme… 

Vibrational modes of Skyrmions

We study the vibrational modes of Skyrmions with baryon numbers one through eight in the standard Skyrme model. The vibrational modes are found in the harmonic approximation around the classical

Higher-order Skyrme hair of black holes

A bstractHigher-order derivative terms are considered as replacement for the Skyrme term in an Einstein-Skyrme-like model in order to pinpoint which properties are necessary for a black hole to

Oscillons in a perturbed signum-Gordon model

A bstractWe study various properties of a perturbed signum-Gordon model, which has been obtained through the dimensional reduction of the called ‘first BPS submodel of the Skyrme model’. This study

Adding crust to BPS Skyrme neutron stars

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

The ϕ4 model with the BPS preserving defect

A bstractThe ϕ4 model is coupled to an impurity in a way that preserves one-half of the BPS property. This means that the antikink-impurity bound state is still a BPS solution, i.e., a zero-pressure

Abstract We consider the quantum multisoliton scattering problem. For BPS theories one truncates the full field theory to the moduli space, a finite dimensional manifold of energy minimising field

Oscillons in the presence of external potential

A bstractWe discuss similarity between oscillons and oscillational mode in perturbed ϕ4. For small depths of the perturbing potential it is difficult to distinguish between oscillons and the mode in

Faddeev models in the low-energy limit of 4 d Yang-Mills-Higgs theories

Firstly, we consider Yang–Mills theory onR with an adjoint Higgs field spontaneously breaking a compact gauge group G to a subgroup H , so that the Higgs vacuum manifold forms the coset G/H . It is



Radial vibrations of BPS skyrmions

We study radial vibrations of spherically symmetric Skyrmions in the Bogomol’nyi-Prasad-Sommerfield Skyrme model. Concretely, we numerically solve the linearized field equations for small

The results are consistent with the interpretation of the deuteron as a quantum state of a toroidal Skyrmion.

Bogomol'nyi-Prasad-Sommerfield Skyrme model and nuclear binding energies.

The classical Bogomol'nyi-Prasad-Sommerfield soliton solutions of the BPS Skyrme model are used together with corrections from the collective coordinate quantization of spin and isospin to calculate nuclear binding energies, finding that the resulting binding energies are already in excellent agreement with their physical values for heavier nuclei.

Loosening up the Skyrme model

We consider the Skyrme model with the addition of extra scalar potentials that decrease the classical binding energies of the Skyrmions to about the 3% level -- without altering the pion mass -- if

States of carbon-12 in the Skyrme model.

The Skyrme model has two Skyrmion solutions of baryon number 12, with D_{3h} and D_{4h} symmetries, with a good match with the ground-state band of carbon-12, and with the recently established rotational band of the Hoyle state.

Light Nuclei of Even Mass Number in the Skyrme Model

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

Deuteron as a soliton in the Skyrme model.

The minimal-energy static soliton solution with baryon number 2 in the Skyrme model is discussed. It is shown that, upon quantizing the spin isospin collective coordinates and taking into account a
