Fermion zero modes in N=2 supervortices
A. Achucarro, A. C. Davis, M. Pickles +1
We study the fermionic zero modes of BPS semilocal magnetic vortices in N=2 supersymmetric QED with a Fayet-Iliopoulos term and two matter hypermultiplets of opposite charge. There…
Nielsen-Olesen strings in Supersymmetric models
M. Pickles, J. Urrestilla
We investigate the behaviour of a model with two oppositely charged scalar fields. In the Bogomol'nyi limit this may be seen as the scalar sector of N=1 supersymmetric QED, and it…
Vortices in Theories with Flat Directions
A. Achucarro, A. C. Davis, M. Pickles +1
In theories with flat directions containing vortices, such as supersymmetric QED, there is a vacuum selection effect in the allowed asymptotic configurations. We explain the role p…
Dynamics and Properties of Chiral Cosmic Strings
M. Pickles, A. C. Davis
Chiral cosmic strings naturally arise in many particle physics models, in particular in supersymmetric theories with a D-term. These strings have a single fermion zero mode in the…
Dynamics and properties of chiral cosmic strings in Minkowski space
A. C. Davis, T. W. B. Kibble, M. Pickles +1
Chiral cosmic strings are produced naturally at the end of inflation in supersymmetric models where the symmetry is broken via a D-term. Consequently in such theories, where both i…
