On exactly solvable Yang-Baxter models and enhanced symmetries
Khalil Idiab, Stijn J. van Tongeren
We study Yang-Baxter deformations of the flat space string that result in exactly solvable models, finding the Nappi-Witten model and its higher dimensional generalizations. We the…
Gauge theory on twist-noncommutative spaces
Tim Meier, Stijn J. van Tongeren
We construct actions for four dimensional noncommutative Yang-Mills theory with star-gauge symmetry, with non-constant noncommutativity, to all orders in the noncommutativity. Our…
Quadratic twist-noncommutative gauge theory
Tim Meier, Stijn J. van Tongeren
Studies of noncommutative gauge theory have mainly focused on noncommutative spacetimes with constant noncommutative structure, with little known about actions for noncommutative 4…
Yang-Baxter deformations of the flat space string
Khalil Idiab, Stijn J. van Tongeren
We define integrability preserving Yang-Baxter deformations of symmetric space sigma models with non-semi-simple symmetry group, in particular the flat space string, using only the…
Coset space actions for nonrelativistic strings
Andrea Fontanella, Stijn J. van Tongeren
We formulate the stringy nonrelativistic limits of the flat space and AdSS string as coset models, based on the string Bargmann and extended string Newton-Hooke algeb…
Do Drinfeld twists of survive light-cone quantization?
Stijn J. van Tongeren, Yannik Zimmermann
We study how a wide class of Abelian Yang-Baxter deformations of the AdSS string behave at the quantum level. These deformations are equivalent to…
Quantum Spectral Curve for the eta-deformed AdS_5xS^5 superstring
Rob Klabbers, Stijn J. van Tongeren
The spectral problem for the superstring and its dual planar maximally supersymmetric Yang-Mills theory can be efficiently solved through a set of fun…
Almost abelian twists and AdS/CFT
Stijn J. van Tongeren
A large class of the recently found unimodular nonabelian homogeneous Yang-Baxter deformations of the AdS_5 x S^5 superstring can be realized as sequences of noncommuting TsT trans…
Abelian Yang-Baxter Deformations and TsT transformations
David Osten, Stijn J. van Tongeren
We prove that abelian Yang-Baxter deformations of superstring coset sigma models are equivalent to sequences of commuting TsT transformations, meaning T dualities and coordinate sh…
Introduction to the thermodynamic Bethe ansatz
Stijn J. van Tongeren
We give a pedagogical introduction to the thermodynamic Bethe ansatz, a method that allows us to describe the thermodynamics of integrable models whose spectrum is found via the (a…
An Integrability Primer for the Gauge-Gravity Correspondence: an Introduction
Diego Bombardelli, Alessandra Cagnazzo, Rouven Frassek +7
We introduce a series of articles reviewing various aspects of integrable models relevant to the AdS/CFT correspondence. Topics covered in these reviews are: classical integrabilit…
On jordanian deformations of AdS_5 and supergravity
Ben Hoare, Stijn J. van Tongeren
We consider various homogeneous Yang-Baxter deformations of the AdS_5 x S^5 superstring that can be obtained from the eta-deformed superstring and related models by singular boosts…
Non-split and split deformations of AdS_5
Ben Hoare, Stijn J. van Tongeren
The eta-deformation of the AdS_5 x S^5 superstring depends on a non-split r matrix for the superalgebra psu(2,2|4). Much of the investigation into this model has considered one par…
Quantum deformations of the flat space superstring
Anna Pachol, Stijn J. van Tongeren
We discuss a quantum deformation of the Green-Schwarz superstring on flat space, arising as a contraction limit of the corresponding deformation of AdS_5 x S^5. This contraction li…

Stijn J. van Tongeren
We give an AdS/CFT interpretation to homogeneous Yang-Baxter deformations of the AdS_5 x S^5 superstring as noncommutative deformations of the dual gauge theory, going well beyond…
Double Wick rotating Green-Schwarz strings
Gleb Arutyunov, Stijn J. van Tongeren
Via an appropriate field redefinition of the fermions, we find a set of conditions under which light cone gauge fixed world sheet theories of strings on two different backgrounds a…
The mirror model as a string
Gleb Arutyunov, Stijn J. van Tongeren
Doing a double Wick rotation in the worldsheet theory of the light cone superstring results in an inequivalent, so-called mirror theory that pl…
On the exact spectrum and mirror duality of the (AdS_5 x S^5)_eta superstring
Gleb Arutyunov, Marius de Leeuw, Stijn J. van Tongeren
We discuss the spectrum of a string propagating on eta-deformed AdS_5 x S^5 by treating its world-sheet theory as an integrable quantum field theory. The exact S-matrix of this fie…
The Quantum Deformed Mirror TBA II
Gleb Arutyunov, Marius de Leeuw, Stijn J. van Tongeren
We discuss the description of generic excited states in the quantum deformed AdS_5 x S^5 mirror thermodynamic Bethe ansatz and derive the associated Y-system. This Y-system shows a…
The spectral problem for strings on twisted AdS_5 x S^5
Marius de Leeuw, Stijn J. van Tongeren
We discuss the spectral problem for integrable superstrings on generically twisted AdS_5 x S^5, meaning all its orbifolds and TsT transformed versions. We explicitly give the asymp…

The spectrum of the light-cone AdS_5 \times S^5 superstring contains states composed of particles with complex momenta including in particular those which turn into bound states in…
Lifting asymptotic degeneracies with the Mirror TBA
Alessandro Sfondrini, Stijn J. van Tongeren
We describe a qualitative feature of the AdS_5 x S^5 string spectrum which is not captured by the asymptotic Bethe ansatz. This is reflected by an enhanced discrete symmetry in the…
Twisting the Mirror TBA
Gleb Arutyunov, Marius de Leeuw, Stijn J. van Tongeren
We study finite-size corrections to the magnon dispersion relation in three models which differ from string theory on AdS5 x S5 in their boundary conditions. Asymptotically, this i…
