Flat-Space Chiral Gravity

TL;DR

This paper presents evidence for a holographic duality between a flat-space gravitational theory derived from topologically massive gravity and a chiral two-dimensional conformal field theory with central charge 24.

Contribution

It establishes the first evidence of a holographic correspondence in flat space between a specific gravity theory and a chiral CFT.

Findings

Holographic duality is supported between flat-space gravity and a chiral CFT.

The gravitational theory is a flat-space limit of topologically massive gravity at level k=1.

The dual field theory is a chiral 2D CFT with central charge c=24.

Abstract

We provide the first evidence for a holographic correspondence between a gravitational theory in flat space and a specific unitary field theory in one dimension lower. The gravitational theory is a flat-space limit of topologically massive gravity in three dimensions at Chern-Simons level k=1. The field theory is a chiral two-dimensional conformal field theory with central charge c=24.
