Sigma models with off-shell N=(4,4) supersymmetry and noncommuting complex structures
M. Goteman, U. Lindstrom, M. Rocek +1
We describe the conditions for extra supersymmetry in N=(2,2) supersymmetric nonlinear sigma models written in terms of semichiral superfields. We find that some of these models ha…
Noncommutative Solitons: Moduli Spaces, Quantization, Finite Theta Effects and Stability
L. Hadasz, U. Lindstrom, M. Rocek +1
We find the N-soliton solution at infinite theta, as well as the metric on the moduli space corresponding to spatial displacements of the solitons. We use a perturbative expansion…
Non-commutative Soliton Scattering
Ulf Lindstrom, Martin Rocek, Rikard von Unge
We study solitons in three dimensional non-commutative scalar field theory at infinite non-commutativity parameter. We find the metric on the relative moduli space of all solitons…
On N=2 low energy effective actions
F. Gonzalez-Rey, U. Lindstrom, M. Rocek +1
We propose a Wilsonian action compatible with special geometry and higher dimension N=2 corrections, and show that the holomorphic contribution F to the low energy effective action…
Supersymmetric sigma-models, twistors, and the Atiyah-Hitchin metric
I. T. Ivanov, M. Rocek
The Legendre transform and its generalizations, originally found in supersymmetric sigma-models, are techniques that can be used to give constructions of hyperkahler metrics. We gi…
The Nonlinear Multiplet Revisited
Byungbae Kim, Ulf Lindström, Martin Roček
Using a reformulation of the nonlinear multiplet as a gauge multiplet, we discuss its dynamics. We show that the nonlinear ``duality'' that appears to relate the model to a convent…
