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…
Anomalous dimensions at four loops in N=6 superconformal Chern-Simons theories
J. A. Minahan, O. Ohlsson Sax, C. Sieg
In arXiv:0908.2463 we computed the four-loop correction to a function depending on the 't Hooft coupling(s) that appears in the magnon dispersion relation of the spin chains derive…
Integrability and the AdS(3)/CFT(2) correspondence
A. Babichenko, B. Stefanski, K. Zarembo
We investigate the AdS(3)/CFT(2) correspondence for theories with 16 supercharges using the integrability approach. We construct Green-Schwarz actions for Type IIB strings on AdS(3…
Odd Chern-Simons Theory, Lie Algebra Cohomology and Characteristic Classes
Jian Qiu, Maxim Zabzine
We investigate the generic 3D topological field theory within AKSZ-BV framework. We use the Batalin-Vilkovisky (BV) formalism to construct explicitly cocycles of the Lie algebra of…
2D and 3D topological field theories for generalized complex geometry
Alberto S. Cattaneo, Jian Qiu, Maxim Zabzine
Using the AKSZ prescription we construct 2D and 3D topological field theories associated to generalized complex manifolds. These models can be thought of as 2D and 3D generalizatio…
Matrix Inflation and the Landscape of its Potential
Amjad Ashoorioon, Hassan Firouzjahi, Mohammmad Mahdi Sheikh-Jabbari
Recently we introduced an inflationary setup in which the inflaton fields are matrix valued scalar fields with a generic quartic potential, M-flation. In this work we study the lan…
New observables in topological instantonic field theories
Andrei Losev, Sergey Slizovskiy
Instantonic theories are quantum field theories where all correlators are determined by integrals over the finite-dimensional space (space of generalized instantons). We consider n…
From weak coupling to spinning strings
Lisa Freyhult, Adam Rej, Stefan Zieme
We identify the gauge theory dual of a spinning string of minimal energy with spins S_1, S_2 on AdS_5 and charge J on S^5. For this purpose we focus on a certain set of local opera…
Holographic Superconductors with Lifshitz Scaling
E. J. Brynjolfsson, U. H. Danielsson, L. Thorlacius +1
Black holes in asymptotically Lifshitz spacetime provide a window onto finite temperature effects in strongly coupled Lifshitz models. We add a Maxwell gauge field and charged matt…
Magnon dispersion to four loops in the ABJM and ABJ models
J. A. Minahan, O. Ohlsson Sax, C. Sieg
The ABJM model is a superconformal Chern-Simons theory with N=6 supersymmetry which is believed to be integrable in the planar limit. However, there is a coupling dependent functio…
Towards Classical de Sitter Solutions in String Theory
Ulf H. Danielsson, Sheikh Shajidul Haque, Gary Shiu +1
We investigate the type II string effective potential at tree-level and derive necessary ingredients for having de Sitter solutions in orientifold models with fluxes. Furthermore,…
Spiky strings in the SL(2) Bethe Ansatz
L. Freyhult, M. Kruczenski, A. Tirziu
We study spiky strings in the context of the SL(2) Bethe ansatz equations. We find an asymmetric distribution of Bethe roots along one cut that determines the all loop anomalous di…
New extended superconformal sigma models and Quaternion Kahler manifolds
Sergei M. Kuzenko, Ulf Lindstrom, Rikard von Unge
Quaternion Kahler manifolds are known to be the target spaces for matter hypermultiplets coupled to N=2 supergravity. It is also known that there is a one-to-one correspondence bet…
Non-linear sigma models via the chiral de Rham complex
Joel Ekstrand, Reimundo Heluani, Johan Kallen +1
We propose a physical interpretation of the chiral de Rham complex as a formal Hamiltonian quantization of the supersymmetric non-linear sigma model. We show that the chiral de Rha…
Geometry of the N=2 supersymmetric sigma model with Euclidean worldsheet
C. M. Hull, U. Lindstrom, L. Melo dos Santos +2
We investigate the target space geometry of supersymmetric sigma models in two dimensions with Euclidean signature, and the conditions for N=2 supersymmetry. For a real action, the…
On the AKSZ formulation of the Rozansky-Witten theory and beyond
Jian Qiu, Maxim Zabzine
Using the AKSZ formalism, we construct the Batalin-Vilkovisky master action for the Rozansky-Witten model, which can be defined for any complex manifold with a closed (2,0)-form. W…
On conformal supergravity and projective superspace
S. M. Kuzenko, U. Lindstrom, M. Rocek +1
The projective superspace formulation for four-dimensional N = 2 matter-coupled supergravity presented in arXiv:0805.4683 makes use of the variant superspace realization for the N…
Finite dimensional AKSZ-BV theories
Francesco Bonechi, Pavel Mnev, Maxim Zabzine
We describe a canonical reduction of AKSZ-BV theories to the cohomology of the source manifold. We get a finite dimensional BV theory that describes the contribution of the zero mo…

Michael C. Abbott, Inês Aniceto, Olof Ohlsson Sax
This paper studies giant magnons in AdS_4 x CP^3 using both the string sigma-model and the algebraic curve. We complete the dictionary of solutions by finding the dyonic generalisa…

W. Chemissany, J. Rosseel, M. Trigiante +1
We prove that all stationary and spherical symmetric black hole solutions to theories with symmetric target spaces are integrable and we provide an explicit integration method. Thi…

Malin Goteman, Ulf Lindstrom
We discuss the conditions for additional supersymmetry and twisted supersymmetry in N = (2, 2) supersymmetric non-linear sigma models described by one left and one right semi-chira…
On Lorentz Invariance, Spin-Charge Separation And SU(2) Yang-Mills Theory
Antti J. Niemi, Sergey Slizovskiy
Previously it has been shown that in spin-charge separated SU(2) Yang-Mills theory Lorentz invariance can become broken by a one-cocycle that appears in the Lorentz boosts. Here we…
Two loop integrability for Chern-Simons theories with N=6 supersymmetry
J. A. Minahan, W. Schulgin, K. Zarembo
We consider two-loop anomalous dimensions for fermionic operators in the ABJM model and the ABJ model. We find the appropriate Hamiltonian and show that it is consistent with a pre…
