Analytic approach to boundary integrability with application to mixed-flux
Julio Cabello Gil, Sibylle Driezen
Boundary integrability provides rare analytic control over field theories with interfaces, from quantum impurity problems to open string dynamics. We propose an analytic approach f…
Integrability for the spectrum of Jordanian AdS/CFT
Sibylle Driezen, Fedor Levkovich-Maslyuk, Adrien Molines
Jordanian deformations offer rare integrable realisations of non-AdS holography, whose solvability methods differ from conventional AdS/CFT examples. Here we study the $\mathfrak{s…
Jordanian spin chains for twisted strings in
Sibylle Driezen, Adrien Molines
We study the proposed integrable spin chain formulation of Jordanian deformations of the superstring, realised via Drinfel'd twists. Among these models, we first…
Particle production in a light-cone gauge fixed Jordanian deformation of
Riccardo Borsato, Sibylle Driezen
We consider a string on a Jordanian deformation of the spacetime. This model belongs to the larger class of Homogeneous Yang-Baxter deformations, which preserve c…
Regularising Spectral Curves for Homogeneous Yang-Baxter strings
Sibylle Driezen, Niranjan Kamath
In this Letter, we study the semi-classical spectrum of integrable worldsheet -models using the Spectral Curve. We consider a Homogeneous Yang-Baxter deformation of the $AdS_5\t…
Exact approaches on the string worldsheet
Saskia Demulder, Sibylle Driezen, Bob Knighton +5
We review different exact approaches to string theory. In the context of the Green-Schwarz superstring, we discuss the action in curved backgrounds and its supercoset formulation,…
Inequivalent light-cone gauge-fixings of strings on backgrounds
Riccardo Borsato, Sibylle Driezen, Ben Hoare +2
Light-cone gauge-fixed sigma-models on backgrounds play an important role in the integrability formulation of the AdS/CFT correspondence. The string spectrum of t…
All Jordanian deformations of the superstring
Riccardo Borsato, Sibylle Driezen
We explicitly construct and classify all Jordanian solutions of the classical Yang-Baxter equation on , corresponding to Jordanian Yang-Baxter deformations o…
Semiclassical spectrum of a Jordanian deformation of
Riccardo Borsato, Sibylle Driezen, Juan Miguel Nieto García +1
We study a Jordanian deformation of the superstring that preserves 12 superisometries. It is an example of homogeneous Yang-Baxter deformations, a class that gen…
Modave Lectures on Classical Integrability in Field Theories
Sibylle Driezen
These lecture notes are based on a blackboard course given at the XVII Modave Summer School in Mathematical Physics held from 13 -- 17 September 2021 in Brussels (Belgium), and aim…
Homogeneous Yang-Baxter deformations as undeformed yet twisted models
Riccardo Borsato, Sibylle Driezen, J. Luis Miramontes
The homogeneous Yang-Baxter deformation is part of a larger web of integrable deformations and dualities that recently have been studied with motivations in integrable -models,…
An Algebraic Classification of Solution Generating Techniques
Riccardo Borsato, Sibylle Driezen, Falk Hassler
We consider a two-fold problem: on the one hand, the classification of a family of solution-generating techniques in (modified) supergravity and, on the other hand, the classificat…
Supergravity solution-generating techniques and canonical transformations of -models from
Riccardo Borsato, Sibylle Driezen
Within the framework of the flux formulation of Double Field Theory (DFT) we employ a generalised Scherk-Schwarz ansatz and discuss the classification of the twists that in the pre…
Integrable -deformations of the Euclidean black string
Sibylle Driezen, Konstantinos Sfetsos
Non-trivial outer algebra automorphisms may be utilized in -deformations of (gauged) WZW models thus providing an efficient way to construct new integrable models. We provide tw…
Open strings in integrable deformations of -models
Sibylle Driezen
This contribution is based on a talk given by the author at the "Dualities and Generalized Geometries" session of the Corfu Summer Institute 2018 workshops. We overview the results…
Integrable asymmetric -deformations
Sibylle Driezen, Alexander Sevrin, Daniel C. Thompson
We construct integrable deformations of the -type for asymmetrically gauged WZW models. This is achieved by a modification of the Sfetsos gauging procedure to account for a poss…
D-branes in -deformations
Sibylle Driezen, Alexander Sevrin, Daniel C. Thompson
We show that the geometric interpretation of D-branes in WZW models as twisted conjugacy classes persists in the --deformed theory. We obtain such configurations by demanding th…
Generalized Kahler structures on group manifolds and T-duality
J. P. Ang, Sibylle Driezen, Martin Rocek +1
We study generalized Kahler structures on N = (2, 2) supersymmetric Wess-Zumino-Witten models; we use the well known case of SU(2) x U(1) as a toy model and develop tools that allo…
Classical and Quantum Aspects of Yang-Baxter Wess-Zumino Models
Saskia Demulder, Sibylle Driezen, Alexander Sevrin +1
We investigate the integrable Yang-Baxter deformation of the 2d Principal Chiral Model with a Wess-Zumino term. For arbitrary groups, the one-loop beta functions are calculated and…
Aspects of the Doubled Worldsheet
Sibylle Driezen, Alexander Sevrin, Daniel C. Thompson
We clarify the relation between various approaches to the manifestly T-duality symmetric string. We explain in detail how the PST covariant doubled string arises from an unusual ga…
