The world next door - Results in landscape topography
Ulf H. Danielsson, Niklas Johansson, Magdalena Larfors
Recently, it has become clear that neighboring multiple vacua might have interesting consequences for the physics of the early universe. In this paper we investigate the topography…
Hyperkahler sigma models on cotangent bundles of Hermitian symmetric spaces using projective superspace
Masato Arai, Sergei M. Kuzenko, Ulf Lindstrom
Kahler manifolds have a natural hyperkahler structure associated with (part of) their cotangent bundles. Using projective superspace, we construct four-dimensional N = 2 models on…
Yang-Mills instanton as a quantum black hole
Sergey Slizovskiy
In terms of spin-charge separated variables, the Minkowski space Yang-Mills BPST instanton describes a locally conformally flat doubly-wrapped cigar manifold that can be viewed as…
T-duality and Generalized Complex Geometry
Jonas Persson
We find the explicit T-duality transformation in the phase space formulation of the N=(1,1) sigma model. We also show that the T-duality transformation is a symplectomorphism and i…
Computing Amplitudes in topological M-theory
Giulio Bonelli, Alessandro Tanzini, Maxim Zabzine
We define a topological quantum membrane theory on a seven dimensional manifold of holonomy. We describe in detail the path integral evaluation for membrane geometries given…
Worldsheet Scattering in AdS_5 x S^5
Thomas Klose, Tristan McLoughlin, Radu Roiban +1
We calculate the S-matrix in the gauge-fixed sigma-model on AdS_5 x S^5 to the leading order in perturbation theory, and analyze how supersymmetry is realized on the scattering sta…
How Accurate is the Quantum String Bethe Ansatz?
Sakura Schafer-Nameki, Marija Zamaklar, Konstantin Zarembo
We compare solutions of the quantum string Bethe equations with explicit one-loop calculations in the sigma-model on AdS(5)xS(5). The Bethe ansatz exactly reproduces the spectrum o…
Spin-Charge Separation, Conformal Covariance and the SU(2) Yang-Mills Theory
Ludvig D. Faddeev, Antti J. Niemi
In the low energy domain of four-dimensional SU(2) Yang-Mills theory the spin and the charge of the gauge field can become separated from each other. The ensuing field variables de…
Generalized Hyperkaehler Geometry and Supersymmetry
Andreas Bredthauer
We propose the definition of (twisted) generalized hyperkaehler geometry and its relation to supersymmetric non-linear sigma models. We also construct the corresponding twistor spa…
Operator Product Expansion for Pure Spinor Superstring on AdS(5)*S(5)
Valentina Giangreco M. Puletti
The tree-level operator product expansion coefficients of the matter currents are calculated in the pure spinor formalism for type IIB superstring in the AdS(5)*S(5) background.
On the covariance of the Dirac-Born-Infeld-Myers action
P. S. Howe, U. Lindstrom, L. Wulff
A covariant version of the non-abelian Dirac-Born-Infeld-Myers action is presented. The non-abelian degrees of freedom are incorporated by adjoining to the (bosonic) worldvolume of…
SIM(2) and Superspace
Ulf Lindstrom, Martin Rocek
In this brief note we give a superspace description of the supersymmetric nonlocal Lorentz noninvariant actions recently proposed by Cohen and Freedman. This leads us to discover s…
Bethe Ansatz in Stringy Sigma Models
T. Klose, K. Zarembo
We compute the exact S-matrix and give the Bethe ansatz solution for three sigma-models which arise as subsectors of string theory in AdS(5)xS(5): Landau-Lifshitz model (non-relati…
Generalized Kahler Geometry from supersymmetric sigma models
Andreas Bredthauer, Ulf Lindstrom, Jonas Persson +1
We give a physical derivation of generalized Kahler geometry. Starting from a supersymmetric nonlinear sigma model, we rederive and explain the results of Gualtieri regarding the e…
Generalized Kahler manifolds and off-shell supersymmetry
Ulf Lindstrom, Martin Rocek, Rikard von Unge +1
We solve the long standing problem of finding an off-shell supersymmetric formulation for a general N = (2, 2) nonlinear two dimensional sigma model. Geometrically the problem is e…
