Hamiltonian of Tensionless Strings with Tensor Central Charge Coordinates
A. A. Zheltukhin, U. Lindström
A new class of twistor-like string models in four-dimensional space-time extended by the addition of six tensorial central charge (TCC) coordinates is studied. The Hamilto…
Kappa-symmetric higher derivative terms in brane actions
P. S. Howe, U. Lindström
Using the superembedding formalism we construct supermembrane actions with higher derivative terms which can be viewed as possible higher order terms in effective actions. In parti…
N=1 supersymmetric sigma model with boundaries, I
Cecilia Albertsson, Ulf Lindstrom, Maxim Zabzine
We study an N=1 two-dimensional non-linear sigma model with boundaries representing, e.g., a gauge fixed open string. We describe the full set of boundary conditions compatible wit…
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…
Strings in a Space with Tensor Central Charge Coordinates
A. A. Zheltukhin, U. Lindström
New string models in D=4 space-time extended by tensor central charge coordinates are constructed. We use the coordinates to generate string tension using a minim…
E8 Quiver Gauge Theory and Mirror Symmetry
Cecilia Albertsson, Bjorn Brinne, Ulf Lindstrom +1
We show that the Higgs branch of a four-dimensional Yang-Mills theory, with gauge and matter content summarised by an E_8 quiver diagram, is identical to the generalised Coulomb br…
N=1 supersymmetric path-integral Poisson-Lie duality
Svend E. Hjelmeland, Ulf Lindström
We extend the path-integral formulation of Poisson-Lie duality found by Tyurin and von Unge to N=1 supersymmetric sigma-models. Using an explicit representation of the generators o…
Strings at the Tachyonic Vacuum
Ulf Lindstrom, Maxim Zabzine
We study the world-volume effective action of Dp-brane at the tachyonic vacuum which is equivalent to the zero tension limit. Using the Hamiltonian formalism we discuss the algebra…
