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…
Divisor braids
Marcel Bökstedt, Nuno M. Romão
We study a novel type of braid groups on a closed orientable surface . These are fundamental groups of certain manifolds that are hybrids between symmetric products and configur…
Spectral curves and the mass of hyperbolic monopoles
Paul Norbury, Nuno M. Romão
The moduli spaces of hyperbolic monopoles are naturally fibred by the monopole mass, and this leads to a nontrivial mass dependence of the holomorphic data (spectral curves, ration…
Slow Schroedinger dynamics of gauged vortices
N. M. Romao, J. M. Speight
Multivortex dynamics in Manton's Schroedinger--Chern--Simons variant of the Landau-Ginzburg model of thin superconductors is studied within a moduli space approximation. It is show…
