These are pedagogical lecture notes discussing current–current deformations of 2-
dimensional field theories. The deformations that are considered here are generated …

We give a covariant realization of the doubled sigma-model formulation of duality-symmetric
string theory within the general framework of para-Hermitian geometry. We define a notion of …

A bstract We study the renormalisation of a large class of integrable σ-models obtained in
the framework of affine Gaudin models. They are characterised by a simple Lie …

A bstract Using a recently developed formulation of double field theory in superspace, the
graviton, B-field, gravitini, dilatini, and Ramond-Ramond bispinor are encoded in a single …

We propose leading order‐corrections to the Poisson‐Lie T‐duality transformation rules of
the metric, B‐field, and dilaton. Based on Double Field Theory, whose corrections to this …

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 classification of …

Generalized parallelizable spaces permit the uplift of many maximal gauged supergravities
to ten or eleven dimensions. Although some of the former are explicitly known, the literature …

A bstract Recent progress in generalised geometry and extended field theories suggests a
deep connection between consistent truncations and dualities, which is not immediately …

We compute the one-and two-loop RG flow of integrable σ-models with Poisson-Lie
symmetry. They are characterised by a twist function with 2N simple poles/zeros and a …
