# T-duality and the bulk-boundary correspondence

## TL;DR

This paper explores how T-duality from string theory can simplify and connect the bulk-boundary correspondence in condensed matter physics, linking position and momentum space perspectives.

## Contribution

It provides a survey of how T-duality relates position and momentum space descriptions of the bulk-boundary correspondence.

## Key findings

- T-duality links position and momentum space pictures.
- Simplifies understanding of bulk-boundary correspondence.
- Provides a unified framework for analysis.

## Abstract

String-theoretic T-duality can be exploited to simplify some features of the bulk-boundary correspondence in condensed matter theory. This paper surveys how T-duality links position and momentum space pictures of that correspondence.
