One-Loop QCD Spin Chain and its Spectrum
N. Beisert, G. Ferretti, R. Heise +1
We study the renormalization of gauge invariant operators in large Nc QCD. We compute the complete matrix of anomalous dimensions to leading order in the 't Hooft coupling and stud…
Transplanckian energy production and slow roll inflation
Ulf H. Danielsson
In this paper we investigate how the energy density due to a non-standard choice of initial vacuum affects the expansion of the universe during inflation. To do this we introduce s…
Matrix models, 4D black holes and topological strings on non-compact Calabi-Yau manifolds
Ulf H. Danielsson, Martin E. Olsson, Marcel Vonk
We study the relation between c=1 matrix models at self-dual radii and topological strings on non-compact Calabi-Yau manifolds. In particular the special case of the deformed matri…
Semiclassical Bethe Ansatz and AdS/CFT
K. Zarembo
The Bethe ansatz can be used to compute anomalous dimensions in N=4 SYM theory. The classical solutions of the sigma-model on AdS(5)xS(5) can also be parameterized by an integral e…
Generalized Kahler geometry and manifest N=(2,2) supersymmetric nonlinear sigma-models
Ulf Lindstrom, Martin Rocek, Rikard von Unge +1
Generalized complex geometry is a new mathematical framework that is useful for describing the target space of N=(2,2) nonlinear sigma-models. The most direct relation is obtained…
T-duality for the sigma model with boundaries
Cecilia Albertsson, Ulf Lindstrom, Maxim Zabzine
We derive the most general local boundary conditions necessary for T-duality to be compatible with superconformal invariance of the two-dimensional N=1 supersymmetric nonlinear sig…
Current Algebras and Differential Geometry
Anton Alekseev, Thomas Strobl
We show that symmetries and gauge symmetries of a large class of 2-dimensional sigma models are described by a new type of a current algebra. The currents are labeled by pairs of a…
Classical/quantum integrability in non-compact sector of AdS/CFT
V. A. Kazakov, K. Zarembo
We discuss non-compact SL(2,R) sectors in N=4 SYM and in AdS string theory and compare their integrable structures. We formulate and solve the Riemann-Hilbert problem for the finit…
Lectures on string theory and cosmology
Ulf H. Danielsson
In these lectures I review recent attempts to apply string theory to cosmology, including string cosmology and various models of brane cosmology. In addition, the review includes a…
Perturbations and Supersymmetries in AdS_3/CFT_2
M. Nishimura, Y. Tanii
Symmetry breaking by perturbations in the AdS/CFT correspondence is discussed. Perturbations of vector fields to the AdS_3 x S^3 solution of the six-dimensional N=(4,4) supergravit…
Bethe ansatz and fluctuations in SU(3) Yang-Mills operators
Lisa Freyhult
We consider the scalar operators corresponding to semiclassical string states in AdS_5xS^5 with the three angular momenta in S^5 non-trivial. The string states recieve quantum corr…
Finite-Size Corrections to Anomalous Dimensions in N=4 SYM Theory
Martin Lubcke, Konstantin Zarembo
The scaling dimensions of large operators in N=4 supersymmetric Yang-Mills theory are dual to energies of semiclassical strings in AdS(5)xS(5). At one loop, the dimensions of large…
Remarks on the black hole entropy and Hawking spectrum in Loop Quantum Gravity
A. Alekseev, A. P. Polychronakos, M. Smedback
In this note we reply to the criticism by Corichi concerning our proposal for an equidistant area spectrum in loop quantum gravity. We further comment on the emission properties of…
Higher Loops Beyond the SU(2) Sector
Joseph A. Minahan
We consider the case of coherent gauge invariant operators in the SU(3) and SO(4) sectors. We argue that in many cases, these sectors can be closed in the thermodynamic limit, even…
Pulsating Strings on AdS_5 x S^5
M. Smedbäck
We find the anomalous dimension and the conserved charges of an R-charged string pulsating on AdS_5. The analysis is performed both on the gauge and string side, where we find agre…
Generalized complex manifolds and supersymmetry
Ulf Lindstrom, Ruben Minasian, Alessandro Tomasiello +1
We find a worldsheet realization of generalized complex geometry, a notion introduced recently by Hitchin which interpolates between complex and symplectic manifolds. The two-dimen…
Dual Superconductors and SU(2) Yang-Mills
Antti J. Niemi
We propose that the SU(2) Yang-Mills theory can be interpreted as a two-band dual superconductor with an interband Josephson coupling. We discuss various consequences of this inter…
Higher Conserved Charges and Integrability for Spinning Strings in AdS_5 x S^5
Johan Engquist
We demonstrate the existence of an infinite number of local commuting charges for classical solutions of the string sigma model on AdS_5 x S^5 associated with a certain circular th…
Invariant star-products on S^2 and the canonical trace
Keizo Matsubara, Mårten Stenmark
In the literature there are two different ways of describing an invariant star product on . We show that the products are actually the same. We also calculate the canonical tr…
Type 0A 2D Black Hole Thermodynamics and the Deformed Matrix Model
Ulf H. Danielsson, James P. Gregory, Martin E. Olsson +2
Recently, it has been proposed that the deformed matrix model describes a two-dimensional type 0A extremal black hole. In this paper, the thermodynamics of 0A charged non-extremal…
A matrix model black hole: act II
Ulf H. Danielsson
In this paper we discuss the connection between the deformed matrix model and two dimensional black holes in the light of the new developements involving fermionic type 0A-string t…
Generalized N=(2,2) Supersymmetric Non-Linear Sigma Models
Ulf Lindstrom
We rewrite the N=(2,2) non-linear sigma model using auxiliary spinorial superfields defining the model on , where is the tangent bundle of the…
