A bstract The worldsheet theories that describe Poisson-Lie T-dualisable σ-models on group
manifolds as well as integrable η, λ and β-deformations provide examples of ℰ-models …

A bstract Prompted by the recent developments in integrable single trace\(T\overline {T}\)
and\(J\overline {T}\) deformations of 2d CFTs, we analyse such deformations in the context …

Integrable deformations of type IIB superstring theory on AdS 5× S 5 have played an
important role over the last years. The Yang–Baxter deformation is a systematic way of …

A bstract We construct supergravity backgrounds for the integrable η-deformations of the
AdS 2× S 2× T 6 and AdS 5× S 5 superstring sigma models. The η-deformation is governed …

We promote the open-closed string map, originally formulated by Seiberg & Witten, to a
solution generating prescription in generalized supergravity. The approach hinges on a …

A bstract Integrable string sigma models on AdS 3 backgrounds with 16 supersymmetries
have the distinguishing feature that their superisometry group is a direct product. As a result …

A bstract For supercosets with isometry group of the form\(\hat {\mathrm {G}}\)×\(\hat {\mathrm
{G}}\), the η-deformation can be generalised to a two-parameter integrable deformation with …

These pedagogical lectures given at the Corfu Summer Institute 2018 review two
generalised notions of T-duality, non-Abelian T-duality and Poisson-Lie duality, and their …

A bstract We construct ad= 11 supergravity analogue of the open-closed string map in the
context of SL (5) Exceptional Field Theory (ExFT). The deformation parameter tri-vector Ω …

A bstract Yang-Baxter deformations of superstring σ-models have recently inspired a
supergravity solution generating technique. Using the open/closed string map and a Killing …
