In this article, the exact BPS spectrum of these models is shown to coincide with the spectrum of massive hypermultiplets of certain = 2 supersymmetric abelian gauge theories in four dimensions.Abstract:
We study = (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 of certain = 2 supersymmetric gauge theories in four dimensions. A special case of these results involves a surprising connection between four-dimensional = 2 SQCD with N colours and N$>Nf>N flavours at the root of the baryonic Higgs branch and the supersymmetric CP2N−Nf−1 σ-model in two dimensions. This correspondence implies a new prediction for the strong-coupling spectrum of the four-dimensional theory.read more

Generalised T-duality and non-geometric backgrounds
Atish Dabholkar,Chris Hull +1 more
TL;DR: In this article, a generalised T-duality transition function is proposed for non-geometric backgrounds in string field theory, which are readily formulated in terms of a doubled geometry, related to generalised geometry.

Vortex strings and four-dimensional gauge dynamics
Amihay Hanany,David Tong +1 more
TL;DR: In this paper, the low-energy quantum dynamics of vortex strings in the Higgs phase of = 2 supersymmetric QCD were studied, and the exact BPS spectrum of the stretched string was shown to coincide with the bimodal spectrum of four-dimensional parent gauge theory, which provided a physical explanation for an observation by Dorey relating the quantum spectra of theories in two and four dimensions.

There are no Goldstone bosons in two-dimensions
TL;DR: In this article, it was shown that in two dimensions the Goldstone phenomenon can not occur; Goldstone's theorem does not end with two alternatives (either manifest symmetry or Goldstone bosons) but with only one (manifest symmetry).

Fivebranes, membranes and non-perturbative string theory
TL;DR: In this article, nonperturbative instanton corrections to the moduli space geometry of type IIA string theory compactified on a Calabi-Yau space are derived and found to contain order e − 1/g s contributions, where g s is the string coupling.

Supersymmetry algebras that include topological charges
Edward Witten,David I. Olive +1 more
TL;DR: In this paper, it was shown that the usual supersymmetric algebra is not valid for supersymmymmetric theories with solitons, and the algebra is modified to include the topological quantum numbers as central charges.
