Are Glueballs Knotted Closed Strings?
Antti J. Niemi
Glueballs have a natural interpretation as closed strings in Yang-Mills theory. Their stability requires that the string carries a nontrivial twist, or then it is knotted. Since a…
On Effective Actions for the Bosonic Tachyon
M. Smedbäck
We extend the analysis of hep-th/0304045 to the bosonic case and find the one-derivative effective action valid in the vicinity of rolling tachyons with an energy not larger than t…
The Supersymmetric Extension of the Faddeev model
Lisa Freyhult
We study the supersymmetric extension of the Faddeev model in four dimensions. The Faddeev model contains three dimensional soliton solutions and we are interested in how these sol…
Yang-Mills Duals for Semiclassical Strings
J. Engquist, J. A. Minahan, K. Zarembo
We consider a semiclassical multiwrapped circular string pulsating on S_5, whose center of mass has angular momentum J on an S_3 subspace. Using the AdS/CFT correspondence we argue…
On Thermalization in de Sitter Space
Ulf H. Danielsson, Martin E. Olsson
We discuss thermalization in de Sitter space and argue, from two different points of view, that the typical time needed for thermalization is of order , where …
Rotating Black Holes in a Goedel Universe
D. Brecher, U. H. Danielsson, J. P. Gregory +1
We construct a five--dimensional, asymptotically Goedel, three--charge black hole via dimensional reduction of an asymptotically plane wave, rotating D1-D5-brane solution of type I…
Time dependent solitons of noncommutative Chern-Simons theory coupled to scalar fields
Leszek Hadasz, Ulf Lindstrom, Martin Rocek +1
We study one- and two-soliton solutions of noncommutative Chern-Simons theory coupled to a nonrelativistic or a relativistic scalar field. In the nonrelativistic case, we find a to…
Comments on Dualities on Group Manifolds and Supersymmetry
Svend E. Hjelmeland, Ulf Lindstrom
We review some facts about various T-dualities and sigma models on group manifolds, with particular emphasis on supersymmetry. We point out some of the problems in reconciling Pois…
Exact Solution of Quantum Field Theory on Noncommutative Phase Spaces
E. Langmann, R. J. Szabo, K. Zarembo
We present the exact solution of a scalar field theory defined with noncommuting position and momentum variables. The model describes charged particles in a uniform magnetic field…
The Schrodinger Wave Functional and Closed String Rolling Tachyon
J. Kluson
In this short note we apply Schrodinger picture description of the minisuperspace approach to the closed string tachyon condensation. We will calculate the rate of produced closed…
The deformed M2-brane
P. S. Howe, S. F. Kerstan, U. Lindstrom +1
The superembedding formalism is used to study correction terms to the dynamics of the M2 brane in a flat background. This is done by deforming the standard embedding constraint. It…
String bits without doubling
Ulf Danielsson, Fredric Kristiansson, Martin Lübcke +1
We construct a string bit model in the pp-wave background in which fermion doubling produces the correct spectrum of string states.
Stringing Spins and Spinning Strings
N. Beisert, J. A. Minahan, M. Staudacher +1
We apply recently developed integrable spin chain and dilatation operator techniques in order to compute the planar one-loop anomalous dimensions for certain operators containing a…
Particle Production on Half S-brane
J. Kluson
In this paper we will study quantum field theory of fluctuation modes around the rolling tachyon solution on non-BPS D-brane effective action. The goal of this paper is to study pa…
Superconformal boundary conditions for the WZW model
Cecilia Albertsson, Ulf Lindstrom, Maxim Zabzine
We review the most general, local, superconformal boundary conditions for the two-dimensional N=1 and N=2 non-linear sigma models, and analyse them for the N=1 and N=2 supersymmetr…
Three Dimensional Gravity From SU(2) Yang-Mills Theory in Two Dimensions
Antti J. Niemi
We argue that two dimensional classical SU(2) Yang-Mills theory describes the embedding of Riemann surfaces in three dimensional curved manifolds. Specifically, the Yang-Mills fiel…
Holography in 4D (Super) Higher Spin Theories and a Test via Cubic Scalar Couplings
E. Sezgin, P. Sundell
The correspondences proposed previously between higher spin gauge theories and free singleton field theories were recently extended into a more complete picture by Klebanov and Pol…
Tensionless Strings, WZW Models at Critical Level and Massless Higher Spin Fields
Ulf Lindstrom, Maxim Zabzine
We discuss the notion of tensionless limit in quantum bosonic string theory, especially in flat Minkowski space, noncompact group manifolds (e.g., SL(2,R)) and coset manifolds (e.g…
Can Renormalization Group Flow End in a Big Mess?
Alexei Morozov, Antti J. Niemi
The field theoretical renormalization group equations have many common features with the equations of dynamical systems. In particular, the manner how Callan-Symanzik equation ensu…
Braneworld holography in Gauss-Bonnet gravity
James P. Gregory, Antonio Padilla
We investigate holography on an (n-1)-dimensional brane embedded in a background of AdS black holes, in n-dimensional Gauss-Bonnet gravity. We demonstrate that for a critical brane…
SL(2,Z) tensionless string backgrounds in IIB string theory
Andreas Bredthauer, Ulf Lindstrom, Jonas Persson
We examine a tensionless limit of a SL(2,Z) set of background solutions to IIB supergravity theory, obtained by performing an infinite boost. This yields a solution that correspond…
Scalar Field Corrections to AdS_4 Gravity from Higher Spin Gauge Theory
Fredric Kristiansson, Peter Rajan
We compute the complete contribution to the stress-energy tensor in the minimal bosonic higher spin theory in D=4 that is quadratic in the scalar field. We find arbitrarily high de…
Exact Solution of Noncommutative Field Theory in Background Magnetic Fields
E. Langmann, R. J. Szabo, K. Zarembo
We obtain the exact non-perturbative solution of a scalar field theory defined on a space with noncommuting position and momentum coordinates. The model describes non-locally inter…
