Compressibility of dense nuclear matter in the -meson variant of the Skyrme model
Miguel Huidobro, Paul Leask, Carlos Naya +1
We show that coupling the -valued Skyrme field to the -meson solves the long-standing issue of (in)compressibility in the solitonic Skyrme model. Even by includi…
Integral identities and universal relations for solitons
Christoph Adam, Alberto Garcia Martin-Caro, Carlos Naya +1
We show that any nonlinear field theory giving rise to static solutions with finite energy like, e.g., topological solitons, allows us to derive an infinite number of integral iden…
Incompressible topological solitons
C. Adam, C. Naya, K. Oles +3
We discover a new class of topological solitons. These solitons can exist in a space of infinite volume like, e.g., , but they cannot be placed in any finite volume,…
Background fields and self-dual Skyrmions
C. Naya, K. Oles
We show that a suitable background field can bring a non-BPS topological soliton into its BPS, self-dual, counterpart. As an example we consider Skyrmions in the minimal Skyrme mod…
Skyrmions and clustering in light nuclei
Carlos Naya, Paul Sutcliffe
One of the outstanding problems in modern nuclear physics is to determine the properties of nuclei from the fundamental theory of the strong force, quantum chromodynamics (QCD). Sk…
Skyrmions in models with pions and rho mesons
Carlos Naya, Paul Sutcliffe
A problem with the standard Skyrme model is that Skyrmion binding energies are around , being much larger than the order binding energies of the nuclei that they aim to…
The Skyrme model in the BPS limit
C. Adam, C. Naya, J. Sanchez-Guillen +2
In this review, we summarise the main features of the BPS Skyrme model which provides a physically well-motivated idealisation of atomic nuclei and nuclear matter: 1) it leads to z…
Baryon chemical potential and in-medium properties of BPS skyrmions
C. Adam, T. Klähn, C. Naya +3
We continue the investigation of thermodynamical properties of the BPS Skyrme model. In particular, we analytically compute the baryon chemical potential both in the full field the…
Topological phase transitions in the gauged BPS baby Skyrme model
C. Adam, C. Naya, T. Romanczukiewicz +2
We demonstrate that the gauged BPS baby Skyrme model with a double vacuum potential allows for phase transitions from a non-solitonic to a solitonic phase, where the latter corresp…
A unified approach to nuclei: The BPS Skyrme Model
C. Adam, C. Naya, J. Sanchez-Guillen +3
We present a concrete model of a low energy effective field theory of QCD, the well-known Skyrme Model. Specifically, we will work with the BPS submodel in order to describe the bi…
BPS Skyrmions as neutron stars
C. Adam, C. Naya, J. Sanchez-Guillen +2
The BPS Skyrme model has been demonstrated already to provide a physically intriguing and quantitatively reliable description of nuclear matter. Indeed, the model has both the symm…
Thermodynamics of the BPS Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +2
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 t…
Nuclear binding energies from a BPS Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +1
Recently, within the space of generalized Skyrme models, a BPS submodel was identified which reproduces some bulk properties of nuclear matter already on a classical level and, as…
Rotational-vibrational coupling in the BPS Skyrme model of baryons
C. Adam, C. Naya, J. Sanchez-Guillen +1
We calculate the rotational-vibrational spectrum in the BPS Skyrme model for the hedgehog skyrmion with baryon number one. The resulting excitation energies for the nucleon and del…
Nonlinear field theory with topological solitons: Skyrme models
C. Adam, C. Naya, J. Sanchez-Guillen +1
In this talk, we give new insight into one of the best-known nonlinear field theories, the Skyrme model. We present some exact relevant solutions coming from different new versions…
Lifshitz field theories with SDiff symmetries
C. Adam, C. Naya, J. Sanchez-Guillen +1
We consider Lifshitz field theories with a dynamical critical exponent z equal to the dimension of space d and with a large group of base space symmetries, concretely space coordin…

C. Adam, C. Naya, J. Sanchez-Guillen +1
The baby Skyrme model is a well-known nonlinear field theory supporting topological solitons in two space dimensions. Its action functional consists of a potential term, a kinetic…
The vector BPS Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +1
We analyze the vector meson formulation of the BPS Skyrme model in (3+1) dimensions, where the term of sixth power in first derivatives characteristic for the original, integrable…
The vector BPS baby Skyrme model
C. Adam, C. Naya, J. Sanchez-Guillen +1
We investigate the relation between the BPS baby Skyrme model and its vector meson formulation, where the baby Skyrme term is replaced by a coupling between the topological current…

C. Adam, C. Naya, J. Sanchez-Guillen +1
The baby Skyrme model is a well-known nonlinear field theory supporting topological solitons in two space dimensions. In the limit where the term quadratic in derivatives (the "sig…
