Rational Skyrmions (2023)
Journal Article
Harland, D., & Sutcliffe, P. (2023). Rational Skyrmions. Journal of Physics A: Mathematical and Theoretical, 56(42), Article 425401. https://doi.org/10.1088/1751-8121/acfbcc

A new method is introduced to construct approximations to Skyrmions that are explicit rational functions of the spatial Cartesian coordinates. The scheme uses ADHM data of a Yang–Mills instanton to produce a Skyrmion with a baryon number that is equa... Read More about Rational Skyrmions.

A Skyrme Model with Novel Chiral Symmetry Breaking (2023)
Journal Article
Sutcliffe, P. (2023). A Skyrme Model with Novel Chiral Symmetry Breaking. Symmetry, integrability and geometry: methods and applications, 19, Article 051. https://doi.org/10.3842/sigma.2023.051

An extension of the Skyrme model is presented in which derivative terms are added that break chiral symmetry to isospin symmetry. The theory contains just one new parameter and it reduces to the standard Skyrme model when this symmetry breaking param... Read More about A Skyrme Model with Novel Chiral Symmetry Breaking.

Q-lump scattering (2023)
Journal Article
Sutcliffe, P. (2023). Q-lump scattering. Journal of High Energy Physics, 2023(6), Article 162. https://doi.org/10.1007/jhep06%282023%29162

Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the mod... Read More about Q-lump scattering.
