Type II DFT solutions from Poisson-Lie T-duality/plurality

Understand

String theory has the T-duality symmetry when the target space has Abelian isometries.

• A generalization of the T-duality, where the isometry group is non-Abelian, is known as the non-Abelian T-duality, which works well as a solution-generating technique in supergravity.
• In this paper, we describe the non-Abelian T-duality as a kind of O(D,D) transformation when the isometry group acts without isotropy.
• We then provide a duality transformation rule for the Ramond-Ramond fields by using the technique of double field theory (DFT).
