Nucleon-antinucleon interaction from the Skyrme model [PDF]
We calculate the nucleon-antinucleon static potential in the Skyrme model using the product ansatz and including some finite $N_C$ (number of colors) corrections. The mid and long range part of the spin-spin and tensor force are correctly given in both iso-spin channels while the central interaction has insufficient mid-range attraction. This is a well

Ab Initio Thermodynamics Calculation of Beta Decay Rates
Beta‐decay half‐lives are calculated ab initio from thermodynamics, independently of any quantum mechanics. The calculated values are close to those experimentally observed. Abstract Beta‐decay half‐lives for the free neutron, for 6He and 8He, and for 8Li are calculated ab initio from geometrical thermodynamics arguments, independently of any quantum ...

Finkelstein-Rubinstein constraints for the Skyrme model with pion masses [PDF]
The Skyrme model is a classical field theory modelling the strong interaction between atomic nuclei. It has to be quantized in order to compare it to nuclear physics.

Microscopic study of nuclear structure for some Si-isotopes using Skyrme-Hartree-Fock-method
In this paper the nuclear structure of some of Si-isotopes namely, 28,32,36,40Si have been studied by calculating the static ground state properties of these isotopes such as charge, proton, neutron and mass densities together with their associated rms ...

Topological Approach of Characterizing Optical Skyrmions and Multi‐Skyrmions
Skyrmions are topologically protected field configurations characterized by a topological index. Here, an intuitive and geometrical method is proposed to determine the index for optical skyrmions solely via their polarization singularities and associated winding numbers.

Nucleon-nucleon potential from skyrmion dipole interactions
We derive the nucleon-nucleon interaction from the Skyrme model using second order perturbation theory and the dipole approximation to skyrmion dynamics. Unlike previous derivations, our derivation accounts for the non-trivial kinetic and potential parts

Abstract Aims and Objective To describe the experiences of nursing care and partnership nursing as expressed by children living with long‐term conditions. Background Children with long‐term conditions have higher rates of hospitalisations and adverse events in hospital, yet little is known about their experiences of nursing care.

Sphalerons in the Skyrme model [PDF]
Numerical methods are used to compute sphaleron solutions of the Skyrme model. These solutions have topological charge zero and are axially symmetric, consisting of an axial charge n Skyrmion and an axial charge -n anti-Skyrmion (with n > 1), balanced in

Investigation of the nuclear structure of 84-108Mo isotopes using Skyrme-Hartree-Fock method
Over the last few decades the mean field approach using selfconsistent Haretree-Fock (HF) calculations with Skyrme effective interactions have been found very satisfactory in reproducing nuclear properties for both stable and unstable nuclei.
