Vortex Harmonic Spinors on the Nappi-Witten Space
Calum Ross, Raúl Sánchez Galán
We establish a correspondence between vortex equations on flat Riemann surfaces and harmonic spinors on the Nappi--Witten space, the group manifold of a central extension of the Eu…

Cartan connections for an infinite family of integrable vortices
Sven Bjarke Gudnason, Calum Ross
An infinite family of integrable vortex equations is studied and related to the Cartan geometry of the underlying Riemann surfaces. This Cartan picture gives an interpretation of t…

Interactions of composite magnetic skyrmion-superconducting vortex pairs in ferromagnetic superconductors
Paul Leask, Calum Ross, Egor Babaev
We study composite topological excitations in ferromagnetic superconductors consisting of bound states of magnetic spin textures (skyrmions) and superconducting vortices. Using a G…
