Mirror Symmetry and Toric Geometry in Three-Dimensional Gauge Theories
Nick Dorey, David Tong
We study three dimensional gauge theories with N=2 supersymmetry. We show that the Coulomb branches of such theories may be rendered compact by the dynamical generation of Chern-Si…
Kinky D-Strings
Neil. D. Lambert, David Tong
We study two-dimensional SQED viewed as the world-volume theory of a D-string in the presence of D5-branes with non-zero background fields that induce attractive forces between the…
Dyonic Instantons in Five Dimensional Gauge Theories
Neil. D. Lambert, David Tong
We show that there exist finite energy, non-singular instanton solutions for five-dimensional theories with broken gauge symmetry. The soliton is supported against collapse by a no…
The BPS Spectra of Gauge Theories in Two and Four Dimensions
N. Dorey, T. J. Hollowood, D. Tong
We study N=(2,2) supersymmetric abelian gauge theories in two dimensions. The exact BPS spectrum of these models is shown to coincide with the spectrum of massive hypermultiplets o…
A Note on 1/4-BPS States
David Tong
We study classical solutions of N=4 super Yang-Mills theories that are invariant under 1/4 of the supersymmetry generators. Expressions for the mass and electric charge of the conf…
