A new perspective on non-commutative deformations of field and gauge theories
Riccardo Borsato, Tim Meier
We construct non-commutative deformations of field and gauge theories based on star-products implemented by Drinfel'd twists. We are able to encompass a large family of twists, inc…
Non-commutative deformations of gauge theories via Drinfel'd twists of the scale symmetry
Riccardo Borsato, Tim Meier
In this paper we consider gauge theories that are relativistic and scale-invariant, and we construct their deformed versions via suitable star products. In particular, the non-comm…
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…
Integrability of the -deformation of the PCM with spectators
Riccardo Borsato, Georgios Itsios, J. Luis Miramontes +1
We construct a generalisation of the -deformation of the Principal Chiral Model (PCM) where we deform just a subgroup of the full symmetry group . We find that demanding…
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…

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…
On the Classical Integrability of Root- Flows
Riccardo Borsato, Christian Ferko, Alessandro Sfondrini
The Root- flow was recently introduced as a universal and classically marginal deformation of any two-dimensional translation-invariant field theory. The flow commu…
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…
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…
Quantum correction to generalized T-dualities
Riccardo Borsato, Linus Wulff
Poisson-Lie duality is a generalization of abelian and non-abelian T-duality, and it can be viewed as a map between solutions of the low-energy effective equations of string theory…

Riccardo Borsato, Alejandro Vilar López, Linus Wulff
We use the -covariant formulation of supergravity familiar from Double Field Theory to find the first -correction to (unimodular) homogeneous Yang-Baxter (YB) deformati…
Two-loop conformal invariance for Yang-Baxter deformed strings
Riccardo Borsato, Linus Wulff
The so-called homogeneous Yang-Baxter (YB) deformations can be considered a non-abelian generalization of T-duality--shift--T-duality (TsT) transformations. TsT transformations are…
Marginal deformations of WZW models and the classical Yang-Baxter equation
Riccardo Borsato, Linus Wulff
We show how so-called Yang-Baxter (YB) deformations of sigma models, based on an R-matrix solving the classical Yang-Baxter equation (CYBE), give rise to marginal current-current d…
Non-abelian T-duality and Yang-Baxter deformations of Green-Schwarz strings
Riccardo Borsato, Linus Wulff
We perform non-abelian T-duality for a generic Green-Schwarz string with respect to an isometry (super)group G, and we derive the transformation rules for the supergravity backgrou…

Riccardo Borsato, Joakim Strömwall, Alessandro Torrielli
We consider the exact -matrix of , which is the building block for describing the scattering of worldsheet excitations of the light-cone gauge-fixed backgrounds $Ad…
-Poincaré supersymmetry in
Riccardo Borsato, Alessandro Torrielli
We consider the exact S-matrix governing the planar spectral problem for strings on and super Yang-Mills, and we show that it is invariant under a…
On non-abelian T-duality and deformations of supercoset string sigma-models
Riccardo Borsato, Linus Wulff
We elaborate on the class of deformed T-dual (DTD) models obtained by first adding a topological term to the action of a supercoset sigma model and then performing (non-abelian) T-…
Integrable deformations of T-dual models
Riccardo Borsato, Linus Wulff
We present a method to deform (generically non-abelian) T duals of two-dimensional models, which preserves classical integrability. The deformed models are identified by a line…
Target space supergeometry of and -deformed strings
Riccardo Borsato, Linus Wulff
We study the integrable and -deformations of supercoset string sigma models, the basic example being the deformation of the superstring. We prove that the…
On the Dressing Factors, Bethe Equations and Yangian Symmetry of Strings on AdS3 x S3 x T4
Riccardo Borsato, Olof Ohlsson Sax, Alessandro Sfondrini +2
Integrability is believed to underlie the AdS3/CFT2 correspondence with sixteen supercharges. We elucidate the role of massless modes within this integrable framework. Firstly, we…
