TL;DR

This paper develops a Lorentz gauge theory of gravity with torsion, showing how Einstein-Hilbert action emerges from quantum torsion effects and proposing an effective theory for cosmic structures at the Planck scale.

Contribution

It introduces a gauge approach to gravity with torsion, demonstrating the induction of Einstein-Hilbert action through quantum corrections and proposing a new effective theory for cosmic knots.

Findings

Einstein-Hilbert action can be induced from a gauge model with torsion.

Quantum torsion corrections lead to a gravito-magnetic condensate.

An effective theory for cosmic knots at Planck scale is proposed.

Abstract

We develop the gauge approach based on the Lorentz group to the gravity with torsion. With a Lagrangian quadratic in curvature we show that the Einstein-Hilbert action can be induced from a simple gauge model due to quantum corrections of torsion via formation of a gravito-magnetic condensate. An effective theory of cosmic knots at Planckian scale is proposed.
