On the geometry of Lagrangian one-forms
Vincent Caudrelier, Derek Harland
Lagrangian multiform theory is a variational framework for integrable systems. In this article we introduce a new formulation which is based on symplectic geometry and which treats…
geometry of hyperbolic monopoles
Guido Franchetti, Derek Harland
It is well-known that the metric on the moduli space of hyperbolic monopoles, defined using the Coulomb gauge-fixing condition, diverges. This article shows that an alternati…
Skyrmion crystals stabilized by -mesons
Derek Harland, Paul Leask, Martin Speight
We investigate the ground state crystalline structure of nuclear matter in the -meson variant of the Skyrme model. After minimizing energy with respect to variations of both the…
Finkelstein-Rubinstein constraints from ADHM data and rational maps
Josh Cork, Derek Harland
We establish simple formulae for computing Finkelstein-Rubinstein signs for Skyrme fields generated in two ways: from instanton ADHM data, and from rational maps. This may be used…
