Linearized Q-Ball Perturbations
Jarah Evslin, Hui Liu, Tomasz Romańczukiewicz +3
Linearized deformations of the thick-walled (low-amplitude) (1+1)-dimensional Q-ball may be decomposed into relativistic modes, which are roughly plane waves, and also long-wavelen…
Quantum Oscillons are Long-Lived
Jarah Evslin, Katarzyna Slawińska, Tomasz Romańczukiewicz +1
As the longest lived transient, oscillons play a critical role in classical field theory simulations of many phenomena. However, beyond the classical approximation, it is well-know…
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…
Radial vibrations of BPS skyrmions
C. Adam, M. Haberichter, T. Romanczukiewicz +1
We study radial vibrations of spherically symmetric skyrmions in the BPS Skyrme model. Concretely, we numerically solve the linearised field equations for small fluctuations in a s…
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…
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…
