Manifestly T-Duality Symmetric Matrix Models

TL;DR

This paper introduces a new class of matrix models that explicitly exhibit T-duality symmetry, enabling nonperturbative analysis and explicit extraction of winding modes in string theory.

Contribution

The paper proposes matrix models with manifest T-duality symmetry, providing a novel nonperturbative regularization framework for continuum string theory.

Findings

Models are explicitly T-duality symmetric.

Winding modes can be extracted using extended matrix variables.

Potential for nonperturbative studies of string dualities.

Abstract

We present a new class of matrix models which are manifestly symmetric under the T-duality transformation of the target space. The models may serve as a nonperturbative regularization for the T-duality symmetry in continuum string theory. In particular, it now becomes possible to extract winding modes explicitly in terms of extended matrix variables.
