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…
Carbon-12 in the generalized Skyrme model
Christoph Adam, Carlos Naya, Andrzej Wereszczyński
We study properties of the C nucleus within the generalized Skyrme model where, in addition to the standard massive Skyrme model, the sextic term and the pionic potential sq…
Fermi arcs, Landau levels and magnetic response of the nematic Weyl liquid
Carlos Naya, Tommaso Bertolini, Johan Carlström
In classes of Weyl semimetals where the symmetry protects nodes with higher than unit charge, the nematic Weyl liquid appears as interactions destroy this underlying symmetry. In t…
Stability of line-node semimetals with strong Coulomb interactions and properties of the symmetry-broken state
Carlos Naya, Tommaso Bertolini, Johan Carlström
We employ diagrammatic Monte Carlo simulations to establish criteria for the stability of line-node semimetals in the presence of Coulomb interactions. Our results indicate a phase…
Skyrmions and Hopfions in 3D Frustrated Magnets
Carlos Naya, Daniel Schubring, Mikhail Shifman +1
A model of an inversion-symmetric frustrated spin system is introduced which hosts three-dimensional extensions of magnetic Skyrmions. In the continuum approximation this model red…
Skyrmion Tubes in achiral nematic liquid crystals
G. De Matteis, L. Martina, C. Naya +1
We analyze the interaction with uniform external fields of nematic liquid crystals within a recent generalized free-energy posited by Virga and falling in the class of quartic func…
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…
Neutron stars within the Skyrme model
Carlos Naya
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 y…
Helicoids in chiral liquid crystals under external fields
G. De Matteis, L. Martina, C. Naya +1
Cholesteric Liquid Crystals (CLCs), subject to externally applied magnetic fields and confined between two parallel planar surfaces with strong homeotropic anchoring conditions, ar…
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…
Neutron stars in the BPS Skyrme model: mean-field limit vs. full field theory
C. Adam, C. Naya, J. Sanchez-Guillen +2
Using a solitonic model of nuclear matter, the BPS Skyrme model, we compare neutron stars obtained in the full field theory, where gravitational back reaction is completely taken i…
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…
BPS Skyrme model and nuclear binding energies
C. Adam, C. Naya, J. Sanchez-Guillen +1
We use the classical BPS soliton solutions of the BPS Skyrme model together with corrections from the collective coordinate quantization of spin and isospin, the electrostatic Coul…
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…
