The metric for hyperbolic 2-monopoles
Guido Franchetti, Derek Harland
It has been recently shown that the notoriously divergent metric on the moduli space of hyperbolic monopoles can be made finite by the introduction of a modified gauge fixi…
A Nahm transform for rotating calorons
Josh Cork, Derek Harland
Rotating calorons were introduced in the context of rotating quark-gluon plasmas. They are anti-self-dual gauge fields on that are invariant under a glide rotation.…
Shape modes of vortices
Nora Gavrea, Derek Harland, Martin Speight
In this paper we investigate the existence of internal modes of vortices in the gauged sigma model. We develop a clean geometric formalism that highlights the symme…
The 3d mixed BF Lagrangian 1-form: a variational formulation of Hitchin's integrable system
Vincent Caudrelier, Derek Harland, Anup Anand Singh +1
We introduce the concept of gauged Lagrangian -forms, extending the notion of Lagrangian -forms to the setting of gauge theories. This general formalism is applied to a natur…
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…
