Einstein Gravity in 2+1 Dimensions from a Gauge Model with Symmetry Breaking
R. Brooks, D. Cangemi, M. Crescimanno
TL;DR
This paper presents a gauge-theoretic formulation of 2+1 dimensional Einstein gravity, where Newton's constant emerges as an order parameter from spontaneous symmetry breaking, and matter coupling is straightforward.
Contribution
It introduces a gauge model framework for 2+1D Einstein gravity with spontaneous symmetry breaking, providing new insights into the origin of Newton's constant.
Findings
Gravity arises from gauge model equations of motion
Newton's constant is an order parameter of symmetry breaking
Matter coupling is simplified in this framework
Abstract
Einstein Gravity in 2+1 dimensions arises as a consequence of the equations of motion of a gauge model in an external metric. Newton's constant appears as an order parameter of a spontaneously broken discrete symmetry. Matter is coupled in a straightforward way.
