Recent progress on dense nuclear matter in skyrmion approaches

YL Ma, M Rho - Science China Physics, Mechanics & Astronomy, 2017 - Springer
The Skyrme model provides a novel unified approach to nuclear physics. In this approach,
single baryon, baryonic matter and medium-modified hadron properties are treated on the …

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

C Adam, C Naya, J Sanchez-Guillen… - Physical Review Letters, 2013 - APS
We use the classical Bogomol'nyi-Prasad-Sommerfield (BPS) soliton solutions of the BPS
Skyrme model together with corrections from the collective coordinate quantization of spin …

Dense matter equation of state and phase transitions from a generalized Skyrme model

C Adam, AG Martín-Caro, M Huidobro, R Vázquez… - Physical Review D, 2022 - APS
Skyrmion crystals are the field configurations which minimize the energy per baryon in the
infinitely large topological charge sector of the Skyrme model, at least for sufficiently high …

Neutron stars within the Skyrme model

C Naya - International Journal of Modern Physics E, 2019 - World Scientific
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 …

[HTML][HTML] BPS Skyrmions as neutron stars

C Adam, C Naya, J Sanchez-Guillen, R Vazquez… - Physics Letters B, 2015 - Elsevier
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 …

Neutron stars in the Bogomol'nyi-Prasad-Sommerfield Skyrme model: Mean-field limit versus full field theory

C Adam, C Naya, J Sanchez-Guillen, R Vazquez… - Physical Review C, 2015 - APS
Using a solitonic model of nuclear matter, the Bogomol'nyi-Prasad-Sommerfield (BPS)
Skyrme model, we compare neutron stars obtained in the full field theory, where …

Skyrmions in models with pions and rho mesons

C Naya, P Sutcliffe - Journal of High Energy Physics, 2018 - Springer
A bstract A problem with the standard Skyrme model is that Skyrmion binding energies are
around 15%, being much larger than the order 1% binding energies of the nuclei that they …

Skyrme models and nuclear matter equation of state

C Adam, M Haberichter, A Wereszczynski - Physical Review C, 2015 - APS
We investigate the role of pressure in a class of generalized Skyrme models. We introduce
pressure as the trace of the spatial part of the energy-momentum tensor and show that it …

Baby Skyrme model, near-BPS approximations, and supersymmetric extensions

S Bolognesi, W Zakrzewski - Physical Review D, 2015 - APS
We study the baby Skyrme model as a theory that interpolates between two distinct BPS
systems. For this, a near-BPS approximation can be used when there is a small deviation …

Thermodynamics of the BPS Skyrme model

C Adam, C Naya, J Sanchez-Guillen, JM Speight… - Physical Review D, 2014 - APS
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 …
