BPS Skyrme models and contact geometry
Radu Slobodeanu, Martin Speight
A Skyrme type energy functional for maps from an oriented Riemannian 3-manifold to a contact 3-manifold is defined, generalizing the BPS Skyrme energy of Ferreira and Z…
Backreacted Coulomb energy in the Skyrme model
Sven Bjarke Gudnason, James Martin Speight
The Skyrme model is extended with the Maxwell action and a source term for the gauge field. We consider the specialized case of vanishing isospin states, such that only an electric…
Nudged Elastic Bands and Lightly Bound Skyrmions
James Martin Speight, Thomas Winyard
It has become clear in recent years that the configuration space of the nuclear Skyrme model has, in each topological class, many almost degenerate local energy minima and that the…
The geometry of the space of vortices on a two-sphere in the Bradlow limit
R. I. Garcia Lara, J. M. Speight
It is proved that the normalized metric on the moduli space of -vortices on a two-sphere, endowed with any Riemannian metric, converges uniformly in the Bradlow limit to t…
Realistic classical binding energies in the -Skyrme model
Sven Bjarke Gudnason, James Martin Speight
An omega-meson extension of the Skyrme model - without the Skyrme term but including the pion mass - first considered by Adkins and Nappi is studied in detail for baryon numbers 1…
The geometry of the space of BPS vortex-antivortex pairs
Nuno M. Romão, J. Martin Speight
The gauged sigma model with target , defined on a Riemann surface , supports static solutions in which vortices coexist in stable equilibrium with anti…
