Recent Developments in the Skyrme Model
Steffen Krusch, Mark Roberts
In this talk, we describe recent developments in the Skyrme model. Our main focus is on discussing various effects which need to be taken into account, when calculating the propert…
Quantization of Skyrmions
Steffen Krusch
The Skyrme model is a nonlinear classical field theory which models the strong interaction between atomic nuclei. In order to compare the predictions of the Skyrme model with nucle…
Finkelstein-Rubinstein constraints for the Skyrme model with pion masses
Steffen Krusch
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. When the Skyr…
Spinning Skyrmions and the Skyrme Parameters
Richard A. Battye, Steffen Krusch, Paul M. Sutcliffe
The traditional approach to fixing the parameters of the Skyrme model requires the energy of a spinning Skyrmion to reproduce the nucleon and delta masses. The standard Skyrme para…
Sphalerons in the Skyrme model
Steffen Krusch, Paul Sutcliffe
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…
Fermions coupled to Skyrmions on S^3
Steffen Krusch
This paper discusses Skyrmions on the 3-sphere coupled to fermions. The resulting Dirac equation commutes with a generalized angular momentum G. For G = 0 the Dirac equation can be…
