Gravitational analog of the Non-Abelian T-duality
Oleg Lunin, Parita Shah
Non-abelian T duality (NATD) is a symmetry of the worldsheet action that allows one to generate new solutions of string theory by performing algebraic transformations of known geom…

Double Field Theory and corrections: explicit examples
Oleg Lunin, Parita Shah
We construct several solutions of effective actions for string theories beyond the supergravity approximation utilizing the framework of the Double Field Theory (DFT). The DFT effe…
