Two-Vierbein Formalism for String-Inspired Axionic Gravity

TL;DR

This paper introduces a two-vierbein formalism inspired by string theory to model graviton and axion fields, enabling a linear realization of O(d,d) duality in a novel way.

Contribution

It proposes a new formalism using independent left and right vierbeins to incorporate axionic gravity within string-inspired models.

Findings

Realizes O(d,d) duality linearly using the two-vierbein approach.

Provides a framework for describing graviton and axion fields simultaneously.

Enhances understanding of duality symmetries in string-inspired gravity theories.

Abstract

Using independent left and right vierbeins to describe graviton plus axion as suggested by string mechanics, O(d,d) duality can be realized linearly.
